Benefits of Trailer Lighting

 

Ring LED Four Function Trailer Lamp

Comfort and safety

The main advantage of Trailer lighting in trailers is better visibility of the vehicle. They shine stronger than halogen lamps, thanks to which they provide better visibility even in fog or rainy weather. What's more, thanks to the use of modern technology, there is no risk that the light will blind another driver. All this contributes to safety and can have a significant impact on avoiding a road collision.

A very big advantage of Trailer lighting is also their reliability over many years. They are much more durable than halogen lamps - usually they ensure correct operation for about 25-50 thousand hours. What's more, there are modern solutions on the market that can burn up to 100,000 hours!

 

Trailer Lighting Standards (SAE Codes & DOT Regulations)

 

All trailer lights must be DOT compliant. It is much more nitty-gritty than most trailer owners will ever need to get, but for the few who DO need it, let's talk about DOT requirements and SAE codes.


Fortunately, it's pretty easy to see if your trailer lights are DOT compliant, since the letters "DOT" will be listed right on the light, reflector, or tape. You'll also see a series of other numbers and letters, such as:


• SAE - Indicates the lens was rated using standards developed by Society of Automotive Engineersedit;


• Codes for individual light functions;


• Year of manufacture;


• Manufacturer's identification number.

 

Many lights can perform more than one function. As an example, the light pictured here has the code "ASTIP2," indicating that this light has the following functions: Rear, front, or side reflector; stop/brake lights; tail lights, rear turn signals, front or rear side marker or clearance lights.


When shopping for trailer lights, you might come across indicators like "PC rated" or "P2 rated". This simply refers to the range of visibility a light is able to cast. PC lights emit a beam that spreads out 90 degrees on each side, giving a total coverage of 180 degrees. This wide visibility makes them perfect for side markers as well as front and rear markers. On the other hand, P2/P3 lights emit beams that spread out 45 degrees on each side, totaling 90 degrees of coverage. While they're visible straight on, they're not clear from the sides of the trailer. Because of this, P2/P3 lights are better suited as front and rear markers.

 

 
Types Of Trailer Lighting
 

Trailer lights are essential when it comes to safety, and making sure to inspect them if they malfunction is imperative. Most trailer lights are shock-resistant, weather-resistant, durable, and can last about 50,000 hours. Here are the lights to check with your local state on to find out if you need them on your trailer. Depending on your trailer, if it is wider than 80 inches, you need extra lights on the side and reflectors on the back. It also depends on your trailer GVWR to determine if it also needs reflective tape and lights. If the GVWR exceeds 15,000, you will require additional lights and reflective tape.

01/

Tail lights – Tail lights or warning lights are on the rear of the trailer. They turn on when you turn on your headlights automatically to keep your trailer visible at night.

02/

Stop Lights – Stop lights, commonly known as brake lights, are on the rear of the trailer. Every time you apply the brake, it turns on to warn other drivers you are slowing.

03/

Turn signals – These flashing lights turn on when you change lanes. Turn signals are also beneficial during severe weather conditions or at night for trailers.

04/

Rear reflex reflector – Reflective lights are critical on a trailer that is more extensive than 80 inches or has a GVWR of above 15,000 since it doesn't rely on lights of its own; it reflects off the headlights of the approaching car.

05/

Side reflex reflector – The side reflex reflectors are mostly installed on trailers for pedestrians, cyclists, and runners to notice the trailer in their route.

06/

License plate lamp – The lamp is a lamp that illuminates your license plate to make it visible your license plate for law enforcement at night and for other drivers to see from a distance.

 

Trailer Lighting Requirements for Trailers Longer than 30 Feet

If you're towing a trailer longer than 30 feet, you must meet the following trailer lighting regulations:

Two tail lights

One license plate light

Two back reflectors

Two marker lights – rear side

Two marker lights – front side

Two reflectors – rear side

Two marker reflectors – front side

Back identification lights

Two intermediate side marker lights

Two intermediate side marker reflectors

Two rear clearance lights

Two front clearance lights

Two stop lights

Two turn signals

In addition to these lights, you must also follow the conspicuity treatments mentioned previously.

 

Common Reasons for the Trailer Lighting Indicator to Appear

 

 

The appearance of the trailer lighting indicator on the vehicle dashboard can be caused by a variety of factors. To shed light on this issue, let's explore the common reasons for this indicator to appear:

 

Faulty Light Bulb: One possible reason for the trailer light indicator to appear is a burnt-out or faulty trailer light bulb. When a bulb is not functioning properly, the indicator will illuminate to alert the driver.

 

Wiring Issues: Another potential cause is wiring problems within the trailer or the vehicle itself. Damaged or loose wiring connections can disrupt the flow of electricity and trigger the indicator.

 

Fuse Problems: A blown fuse can also lead to the appearance of the trailer light indicator. Fuses protect the electrical circuit by breaking it when there is excessive current flow. If a fuse related to the trailer lights blows, the indicator will be activated.

 

Faulty Trailer Light Control Module: Modern vehicles often feature a trailer light control module that regulates the trailer lights. If this module malfunctions, it can trigger the indicator on the dashboard.

 

It's important to note that these are just some common reasons for the trailer light indicator to appear. Other factors like water damage, corrosion, or a malfunctioning vehicle computer system can also contribute to this issue. If the indicator persists, it is recommended to consult a professional mechanic to diagnose and resolve the problem effectively. It's worth considering the unique details related to the specific make and model of your vehicle. Each vehicle may have its own set of peculiarities that can contribute to the appearance of the trailer light indicator.

 

Two Materials for Trailer Lighting Lenses
 

Trailer lighting are exposed to the elements probably more so than any other vehicle and lights being the most delicate part of the trailer tend to bear the brunt of this. Vibration, rocks and road stone, dust, rain and sun all take their toll on lights over time and depending on the end use of your trailer, buying the right type of lens can increase the lights life span.

 

Trailer lighting lenses come in both acrylic and polycarbonate and there are some significant differences between them.

 

Polycarbonate is a popular choice for light lenses as they are almost impossible to break. They are very strong and have a high resistance to impact from stones or objects. Protective glasses and car headlights are normally made from polycarbonate because of this reason.

 

Acrylic although strong, does not have the same impact resistance as polycarbonate and will, if hit hard enough, shatter. Some manufacturers use a high impact acrylic formula for their lights and this increases the lights resistance to most impacts.

 

Acrylic lenses have an excellent resistance to scratching and damage from abrasion. One of polycarbonates weaknesses is its natural tendency to scratch easily. There are special manufacturer applied coatings that can increase the resistance to scratches and abrasion and you will normally pay more for coated lenses.

 

Acrylic does have excellent resistance to UV damage. Coloured lenses will not fade and clear lenses will not yellow or craze (Micro cracks on the surface) like polycarbonate lenses will, and this makes acrylic lenses ideal for trailers that are exposed to high levels of sunlight. There are again, manufacturer supplied UV coatings that can be applied to polycarbonate lenses to prevent fading and yellowing.

 

Lastly, acrylic has good chemical resistance. Some polycarbonates can glaze over even when washed using a strong detergent or when exposed to petrochemicals (petrol, oil, solvents). If you have or fit polycarbonate lens lights to your trailer, wash them only with water and a mild detergent.

Is Contour Lighting Compulsory According to the Rules on Trailer Lighting

Having contour lights on a trailer is compulsory under certain circumstances. This category of LED lights on a trailer can be found on the front, side and rear of the trailer. The legal requirements for contour lighting on a trailer, the following rules apply.

Contour illumination on front and rear of trailer:
For trailers wider than 2.10 metres, two marker lights must be fitted at both the front and rear of the trailer. As normally, the colour of the front of the trailer must be white and the colour of the LED marking lights at the rear must be red.

Orange/amber-coloured LED markings must be placed on the side of the trailer if the trailer is longer than six (6) metres.

 

 

Steps to Install Trailer Lighting

Step 1: Removing the Old Lights
First, remove the existing lights from your trailer. Keep the screws or bolts if they are in good condition; they can be reused to install the new lights. If you have a light that is mounted with a rubber grommet (recessed mount), you can use a screwdriver to pry out the light and grommet from its cutout to disconnect the plug/wires.

 

Step 2: Cutting and Stripping the Wires
Next, if your existing lights do not have a connector to disconnect their wiring, you'll need to cut the wires connecting to the old lights. It is better to cut closer to the light end to leave as much wire length as possible. Once the wires are cut, use a wire stripper to remove about 1/4 inch of insulation from each wire end.
If the old lights were connected with plugs and weren't damaged upon removal, and there's no damage to the wiring harness, you can skip this step and simply just attach your new LED trailer lights to the existing connection.

 

Step 3: Connecting the Wires
Now it's time to connect the wires. Each LED light will usually have a ground wire (often white), a tail light wire (often brown or black), and a turn signal/brake light wire (often green for the right and yellow or red for the left). Attach the corresponding wires from your trailer to the wires on the LED lights.
If the light being replaced has a plug that is in good condition and matches your new light, you can plug your new light into the existing connector.
To secure the new connections, use butt/bullet connectors or solder the wires and then cover them with heat-shrink tubing.

Step 4: Grounding the Lights

LED lights need to be grounded properly to function. Most trailer harnesses have a white wire that is used for grounding. The white wire should be connected to the metal frame of your trailer. If you have a single-wire, self-grounding light, this means it grounds itself through the mounting hardware (e.g. screws).

Step 5: Installing the New LED Lights

Attach the main lights to the rear of your trailer using the provided screws or your old ones. If required, drill holes for the screws. Follow the same process for any additional lights.
Generally, if the light is recessed/grommet mount, you will already have the needed cutouts for replacing the lights, but if it is a new trailer or you are changing the style of lights, you will also need a saw for making a cutout for a recessed or grommet mount light.

Step 6: Testing the Lights

Once everything is installed, it's time to test the lights. Hook up your trailer to your vehicle, turn on your vehicle's lights, and then walk around the trailer to check each light. Test the turn signals and brakes as well. If any light does not work, check the wiring connections and make sure the light is properly grounded.
Remember, safety should always be a priority. If you're not comfortable doing this yourself, or if the lights are still not working after installation, don't hesitate to contact a professional.

Q: Are trailer lighting required?

A: According to the department of transportation, yes, certain trailer lights are required. The tough part is it can be different for each state. The following must be on your trailer to have it road-ready no matter where you live:
· 2 red brake lights
· 2 turn signals (yellow or red)
· License plate light
· 2 yellow front side lights
· 2 red rear side lights

Q: Are trailer lighting required during the day?

A: Trailer lighting are required to be functional no matter what time of day it is. Your brake lights and turn signals are the most important lights on your trailer. Making sure these lights work will keep you and others safe on the road at all times.

Q: Do trailer lighting need to be grounded?

A: It would be best if you ground individual trailer lights lamps need to be grounded through the wiring of the trailer harness. Lights not adequately grounded to your trailer will have irregular or no illumination when you apply them on the brake. To ground the trailer wire, ensure the white wire plug is correctly connected to the tongue of the trailer, and it will use the trailer as a ground wire.

Q: Do trailer lighting have fuses?

A: Yes and no. Trailers themselves do not have fuses but rely on the fuses of a car. If there are malfunctioning car lights, it is a good indicator that you may have trailer lights that don't work as well.

Q: Do trailer lighting drain the battery?

A: If your trailer lights are not solar-powered or wireless, they will take power from a battery source, causing your battery to drain. If you hook up your vehicle to a trailer overnight, it could also drain your battery. If the battery on your car keeps dying overnight even though your engine and interior lights are off, your battery could have problems caused by short circuits.

Q: What are the types of trailer lighting?

A: Trailer lights are essential when it comes to safety, and making sure to inspect them if they malfunction is imperative. Most trailer lights are shock-resistant, weather-resistant, durable, and can last about 50,000 hours. Here are the lights to check with your local state on to find out if you need them on your trailer. Depending on your trailer, if it is wider than 80 inches, you need extra lights on the side and reflectors on the back. It also depends on your trailer gvwr to determine if it also needs reflective tape and lights. If the gvwr exceeds 15,000, you will require additional lights and reflective tape.

Q: What happens if trailer lighting stops working?

A: · If your trailer lights are not working, the first thing you can do is make sure the bulbs are good. If you have a bad bulb, it won't work even with a power source providing the adequate energy needed.
· The second thing you can do is check the fuses in your vehicle, as discussed above. If there is a bad connection for some reason, it will cause malfunctions.
· Third, if the trailer lights are not grounded, they will not work correctly.

Q: Does trailer lighting require an adapter?

A: A trailer light adapter is a light and electric connector between cars and a trailer that gives your trailer three lights; braking, turn, and running lights.

Q: How do I wire trailer lighting?

A: Start attaching and organizing trailer wirings and insert the wire into the casing. To make it easy, you can slice the case to insert the wire and tape the ends of the wiring to make sure moisture doesn't get inside. You can now start securing the wiring using plastic loop clips and begin running wire to the rear of the trailer.

Q: How do I test trailer lighting?

A: We have to check if everything is working appropriately. You must check the brake lights, turning signals, reverse lights, and running lights. If you have a problem with trailer lights, check if the wires have a good connection, if the ground wiring is good, and if you may have a bad wire power from the front trailer and car connection.

Q: Which trailer lighting do you need?

A: No matter what type of trailer you have, trailer lighting regulations require you to have the following lights:
Stop lights;
Tail lights;
Turn signals;
Reflectors.
If your trailer is 80-inches wide or longer than 30 feet, then you need more reflectors and lights.

Q: Do trailer lighting have their own fuse?

A: Yes they do, the issue here is the trailer wiring circuits and new vehicles that come from the factory with the tow package (hitch installed) have a separate wiring system just for the trailer. This is actually good because the vehicle lights keep working properly even if there is a problem with the trailer system. Ok so look in the index of the manual and find fuses, turn to that page and start looking for the one labeled TR running lights or it may even say trailer running/clearance. Locate that fuse in the correct fuse box and check to see if it's good.

Q: Will my trailer lighting work without a battery?

A: A trailer's battery would not affect the trailer lighting functions as they are not powered from the battery. If I had to guess I'd say that the trailer wiring was possibly damaged when someone removed the battery or you have a weak ground for the lighting on that side of the trailer.

Q: How to get trailer lighting to work?

A: Checking and replacing bulbs may be all that is required, but if not, you'll need to look at the wiring. Many trailer problems are due to a poor grounding connection, which is usually the white wire coming out of the trailer plug. If the ground is poor, lights may work intermittently or not at all. Even if the wiring to the plug is adequate, make sure that the ground connections to the trailer frame are good. They should be bright and clean, free from paint and rust, and secure. If you operate one of the turn signals and the brake lights glow, or the lights are not as bright as they should be, suspect that the ground is the cause.

Q: What to do if you have no trailer lighting?

A: You may need to replace the fuse or fix the connecting points. The grounding location is the cause of the malfunction if you notice the signal output enters the box without coming out or sends power to the wrong wires. It's also important to check if cut or pinched harnesses are the cause.

Q: What are trailer lighting used for?

A: Trailer lights are required to be functional no matter what time of day it is. Your brake lights and turn signals are the most important lights on your trailer. Making sure these lights work will keep you and others safe on the road at all times.

Q: Are LED trailer lighting worth it?

A: LED lights use less electricity than incandescent bulbs and last longer, so you don't need to replace them as often, all of which means LED trailer lights can help cut your monthly expenses without compromising visibility.

Q: What are the benefits of installing trailer lighting?

A: Firstly, LED lights are much brighter than traditional incandescent lights, making your trailer more visible on the road. This increased visibility can help prevent accidents and keep you and other drivers safe.
Additionally, LED lights are more energy-efficient, meaning they consume less power and can save you money on fuel costs. Lastly, LED lights have a longer lifespan than incandescent lights, reducing the need for frequent replacements.

Q: Does your trailer lighting need maintenance?

A: LED trailer lights are an innovative solution for trailer lighting. With their low energy consumption, durability, and long lifespan, LED lights offer significant advantages over traditional incandescent lights. These trailer lights are designed to provide bright and efficient lighting, enhancing visibility and safety on the road. LED lights also require less maintenance and are resistant to shock and vibration, making them ideal for trailers that frequently encounter rough terrains.
