Brighten up your driving experience with this simple upgrade inside your fuse box. Simply install the GM All Lights On Module to allow your high-beams, low-beams and fog lamps to simultaneously illuminate the road ahead.
Once installed the GM All Lights On Module will turn on the high-beams, low beams and fog lamps when you turn on your high-beams. When the high-beams are not turned on your low-beams and fog lights will function normally.
Add the supplied spade terminal to provide a signal ground when the high-beams are turned on. This will allow you to control an accessory relay with the high-beam switch.
Warning: The spade terminal signal ground is NOT intended to provide a high amperage ground. It is only rated for a signal ground that will control a relay.
