Light hookup for trailer

When towing a trailer, it is important to have proper lighting to ensure safety on the road. In this article, we will discuss the different types of light hookups for trailers and how to properly install them.

Types of Light Hookups

There are two main types of light hookups for trailers: the four-way flat and the seven-way round.

It consists of four wires: the white wire for the ground, the brown wire for the running lights, the yellow wire for the left turn signal and brake light, and the green wire for the right turn signal and brake light.

Seven-Way Round

The seven-way round hookup is typically used for larger trailers such as RVs or horse trailers. It consists of seven wires: the white wire for the ground, the brown wire for the taillights, the yellow wire for the left turn signal and brake light, the green wire for the right turn signal and brake light, the blue wire for electric brakes, and the black and red wires for auxiliary power or reverse lights.
