The MLToys Lighting Kit already comes with this switch. But some customers want to have extra switches to turn on/off accessories such as underglows, foglights, and the volt/fuel gauge individually. With this switch you simply cut one of the wires going to the accessory and splice the wires to it. Polarity doesn't matter, nor does it matter if you cut the black or red wire.

Comes with solder-free spade connectors.
