Tow a trailer with LED lights using a vehicle equipped with a standard 7-way RV blade socket and lamp-out monitoring system. Built-in resistors simulate the electrical load of incandescent lights so compatible vehicle computers can recognize the trailer lighting correctly.
Curt 57003 installs between the vehicle's existing 7-way RV blade socket and the trailer's 7-way RV blade plug. Integrated resistors increase the electrical load seen by the tow vehicle, allowing compatible lamp-out monitoring systems to properly recognize trailers equipped with low-draw LED lighting.
The plug-and-play design requires no cutting or splicing and retains all seven trailer wiring functions, including tail, brake, reverse, turn signal, electric brake, auxiliary power, and ground circuits. Durable black plastic construction and a spring-loaded cover help protect the connection during regular towing use.
Installs between a standard 7-way RV blade vehicle socket and trailer plug
Allows compatible vehicle computers to properly recognize low-draw LED trailer lights
Simulate the electrical load needed for lamp-out monitoring systems
Simply plugs into the existing vehicle and trailer wiring connections
Curt 57003 is intended for vehicles whose monitoring systems do not properly recognize the low electrical draw of LED trailer lights. The built-in resistors allow the vehicle to detect the trailer lighting load normally.
Curt specifies that 57003 is an electrical adapter only and is not intended to provide additional wiring length between the tow vehicle and trailer.
In The Package: • Curt 57003 7-Way RV Blade LED Electrical Adapter
This adapter is especially useful on vehicles equipped with lamp-out monitoring systems that interpret the low current draw of LED trailer lights as a bulb failure. Verify the vehicle uses a standard 7-way RV blade socket before ordering.
