In this article, we will discuss everything you need to know about 3 wire LED trailer light wiring diagram in a simplified language that anyone can understand. Read on to learn more.

What are 3 Wire LED Trailer Lights?

Before diving into the wiring diagram, it is important to understand what 3 wire LED trailer lights are. As the name suggests, these lights have three wires- one for the brake light, one for the tail light, and one for the turn signal/indicator light. These lights are energy-efficient, consume low power, and are long-lasting, making them a popular choice among trailer owners.

Components of 3 Wire LED Trailer Lights

Before proceeding to the wiring diagram, let’s first take a look at the components that make up 3 wire LED trailer lights:

Component Description
LED Bulbs Energy-efficient and long-lasting bulbs that emit bright light
Reflector Reflects the light emitted by the LED bulb, making it more visible
Lens Cover that protects the LED bulb and the reflector from damage
Wires Connects the LED bulb to the trailer’s electrical system

Wiring Diagram for 3 Wire LED Trailer Lights

The wiring diagram for 3 wire LED trailer lights is relatively simple, provided you follow the right steps. Here is the step-by-step guide:

Step 1: Disconnect the Trailer from the Vehicle

Before starting the wiring process, make sure that the trailer is disconnected from the vehicle’s electrical system. This ensures that there is no risk of electrocution or damage to any component.

Step 2: Identify the Wires

Next, identify the wires that connect the trailer lights to the electrical system. Typically, there are four wires- one for the brake light, one for the tail light, one for the turn signal/indicator light, and one ground wire. In a 3 wire LED trailer light, the ground wire is shared between the brake and tail light.

Step 3: Connect the Wires to the LED Lights

Once you have identified the wires, connect them to the corresponding terminals on the LED light. The brake light wire goes to the positive terminal on the LED light, the tail light wire goes to the negative terminal, and the turn signal wire goes to the turn signal terminal. If your LED light has a separate ground terminal, connect it to the ground wire.

Step 4: Test the Lights

Once the wiring is complete, test the lights by connecting the trailer to the vehicle’s electrical system. Turn on the headlights, and check if the brake, tail, and turn signals are working correctly. If everything is functioning as expected, you can proceed to secure the LED lights onto the trailer.

FAQs

Q1: What is the difference between 2 wire and 3 wire LED trailer lights?

2 wire LED trailer lights have two wires- one for the brake light and one for the tail light. On the other hand, 3 wire LED trailer lights have three wires- one for the brake light, one for the tail light, and one for the turn signal/indicator light.

Q2: Can I use a 3 wire LED trailer light for both brake and turn signals?

Yes, you can use a 3 wire LED trailer light for both brake and turn signals. In this case, you need to connect the turn signal wire to the brake wire using a converter.

Q3: How do I know if my 3 wire LED trailer lights are working?

To test if your LED trailer lights are working, connect the trailer to the vehicle’s electrical system and turn on the headlights. Press the brake pedal to check if the brake lights are working. Turn on the turn signals to see if the indicator lights are flashing. Finally, turn off the headlights to check if the tail lights are working.

Q4: How long do 3 wire LED trailer lights last?

3 wire LED trailer lights are known for their long life span, which can range from 30,000 to 100,000 hours or more depending on the quality of the LED and its components.

Q5: Can I install 3 wire LED trailer lights myself?

Yes, you can install 3 wire LED trailer lights yourself, provided you have basic knowledge of electrical wiring and follow the manufacturer’s instructions carefully.

Conclusion

3 wire LED trailer light wiring diagrams might seem complicated, but they are relatively easy to understand with a little bit of know-how. By following the instructions in this article, you can install 3 wire LED trailer lights on your own and enjoy a safe and hassle-free towing experience.
