Power Converters

WHEN DO I NEED A TAILLIGHT CONVERTER?
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.

CHOOSING THE RIGHT CONVERTER
The converter you choose depends on the type of trailer you'll be towing and the car or truck you'll be towing it with. Be sure to consult your owner's manual for their recommendations.
