trailer lights what are the requirements
The legal requirements for trailer lights can be grouped into two classes: trailers less than 80 wide, and those that are more than 80 wide. Trailers less than 80 wide are required to have tail lights, stop lights, turn signals, side marker lights and side and rear reflectors on each side. You must also have a license plate light and, on trailers over certain lengths, additional side marker lights and side reflectors are necessary.
