Trailer lights are an essential safety feature for any vehicle that tows a trailer. They allow other drivers to see the trailer at night and in low-visibility conditions, which helps to prevent accidents. Trailer lights are typically powered by the vehicle’s electrical system, and they are connected to the trailer using a wiring harness.
There are a few different types of trailer lights, including taillights, brake lights, turn signals, and clearance lights. Taillights and brake lights are required by law in most jurisdictions, while turn signals and clearance lights are optional. However, it is always a good idea to have all of these lights installed on your trailer, as they can help to improve safety.
