When Do I Need A Power Converter?

A converter is required when the towing vehicle has separate wires for brake lights and turn signals. Converters provide power directly from the battery, bypassing the electronics on vehicles that can not handle the extra amp load that trailer lights require. Most trailers operate on a two wire system where the brake lights and turn signals operate on the same wire. When the towing vehicle has separate wires for brake lights and turn signals, a taillight converter is required. The converter you choose must be based on the type of vehicle and trailer you are towing.
