Boat Trailer Wire Colors

By | August 16, 2022



When it comes to connecting the lights on a boat trailer, it is essential to use the proper color-coded wiring. The right wires help make sure you can be seen at night and are properly illuminated when turning in traffic. To ensure you have the best wiring possible, let’s take a look at the right colors for your boat trailer wire.

The most common trailer wire colors are red, black, green, white, yellow, brown, and blue. Red generally functions as the tail lights, turn signals, and brake lights while the black wire functions as the ground and the white wire works as the reverse light in case you need to back up your boat trailer. The other colors are typically used as accessory wires or in special cases where extra power is needed.

It is important to make sure the wiring of your boat trailer matches the manufacturer’s instructions and that all the wires are insulated correctly so that they don’t cross and cause short-circuiting. It is also important to only use cords that are weatherproof and designed for outdoor use. Be sure to leave enough length on each cord so that they can easily be routed through the frame of the trailer as well as threaded around bulky parts or across sharp edges.

With the right colors, proper insulation, and the right length, your boat trailer will be properly illuminated for safety while enjoying a great day out on the water. Remember to check your connections frequently and to take the necessary time to make sure your wiring is done correctly!
