Trailers require electrical hook-ups that make towing safer for you and others on the road. In fact, while each state has its own laws and regulations governing everything from size limits to weight restrictions, the one thing they all have in common is that your trailer must be wired for tail lights, brake lights and turn signals. This is accomplished by connecting your trailer to your vehicle’s electric system. Unfortunately, not all trailer electrical wiring is compatible with the wires of your car, truck, van or SUV. Fortunately, REESE® Towpower manufactures a full line of trailer electrical components for everything you need to get your trailer lights up and running for safe towing. We manufacture T-Connectors, wiring converters, wiring connectors, adapters, brake controls and more to make towing safe for you and the drivers around you. Best of all, our products install quickly and easily with simple do-it-yourself instructions.
