Trailer Light Wiring Color On A 2021 Ford Superduty

By | August 27, 2023



If you’re planning to haul a trailer with your 2021 Ford Superduty, you need to make sure your trailer light wiring color is up to code. Knowing the proper color coding for trailer lights can save you a lot of time and headaches, so it’s important to get it right.

It’s worth noting that the trailer light wiring color standards vary from state to state, so you should check your local regulations before you hook up your trailer. Generally speaking, however, the most common colors used for trailer light wiring are brown, yellow, green, red, and white. Brown is often used for the running lights and license plate illumination; yellow is used for the left-turn signal and taillights; green is usually used for the right-turn signal and brake lights; red is typically used for the reverse lights; and white is used for ground.

When wiring your trailer lights, it’s also important to make sure the connections are secure and waterproof. If there’s an issue with your trailer wiring, it could be a safety hazard, so it’s best to double-check your trailer light wiring color and connections before you hit the road. With the right knowledge and care, you can make sure your trailer lights are ready to go for your 2021 Ford Superduty.
