Trailer lights are an important safety feature and are required for all trailers hauled on the road. Trailer electrical wiring is used to power trailer brake lights, tail lights, turn signals, trailer clearance lights, and side marker lights. Trailer wiring harnesses and connectors are used to connect the trailer's lights to the tow vehicle. Most typical trailer connectors are four- or five-pin electrical converters designed to convert the vehicle's wiring system to be compatible with the trailer. The most common connector is a four-way flat connector, which has four wires that control the trailer's brake lights, tail lights, turn signals, and the ground. Five-way and seven-way connectors may also be present on your trailer, especially if it's equipped with optional accessories like electric trailer brakes. If your trailer's lights are not working but you don't see any sign of damage, you may have a problem with the trailer wiring, connectors, or wiring harness.
