The Trailer Light Circuit Protector is a trailer light power supply that provides power to the trailer lights directly from the tow vehicle’s battery. By powering the trailer lights in this manner, the tow vehicle’s tail, turn and stop light circuits are not exposed to any additional loads. In many cases the tail, turn and stop light circuits of today’s vehicles are connected with light gauge wire, designed only to carry enough current to supply the lights the vehicle is equipped with. Additionally, some vehicles are equipped with sensitive electronic devices, such as "lamp-out" sensors, which are designed to monitor the vehicle’s electrical system and warn the driver of problems with that system. The additional load of trailer lights on these devices can cause them to react falsely and in some cases may lead to their failure.

• Some vehicle’s tail, turn and stop light circuits are not adequate to carry the additional load of trailer lights, making it necessary for them to require a trailer light circuit protector.  Serious damage to the vehicle’s electrical system may result if a trailer light circuit protector is not used. Consult your REESE dealer or REESE Customer Service about your specific vehicle.

• Vehicle manufacturer’s caution consumers against adding additional loads to electrical circuits. Consult the vehicle owner’s manual when recommending trailer wiring. The trailer light circuit protector also takes the place of a tail light converter. The unit can be used on vehicles that have separate tail, turn and stop light circuits and converts them to standard trailer light wiring configuration.  It also features a hazard flasher override circuit. If the hazard flashers are engaged and brakes are applied, brake lights will be shown on the trailer. This is an added safety feature that most tail light converters do not provide.

• Because the unit receives its power directly from the tow vehicle’s battery and not the turn signal circuit, the need for a heavy duty turn signal flasher is eliminated. The heavy duty trailer light circuit protector is capable of supplying up to 10 amps per circuit of power to the trailer lights. The regular duty circuit protector is capable of supplying up to 4 amps per circuit, of power to the trailer lights. This, combined with its advanced circuitry, provides maximum trailer light brightness. A 4-flat is provided.

• To determine which circuit protector you may need, follow these basic guidelines. Add the number of amps required on the trailer you will be towing. If the number of amps exceeds 4 per light circuit, you will need to use the REESE heavy duty model.  1) Stop-Turn lights = 2 amps each. 2) Tail lights = 1 amp each. 3) Clearance/Marker lights = 1/2 amp each.

NOTE: The regular and heavy duty circuit protectors can be used on vehicles that both do and do not require a converter (2 or 3 wire systems.)
