hitch reverse lights

This is a powered 2" receiver hitch back up system. When the car is put in reverse, the 9 LED's light up bright white. This can alternately be used with red LED's as a brake light system. The print is 3 pieces plus hardware and electronics.
If you are wiring for reverse lights, please get a professional to do the wiring- there needs to be a dedicated pair of wires run inside the vehicle for the reverse. (unless you have 6 or 7 pin harness on the vehicle.) You also need to have a disconnect between this design and the vehicle.
