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.
2003-2007 Classic 1500, 2500, 3500 Silverado/Sierra and full size GM - or - if your fuse box is laid out like the one shown below
1. Remove the relays labeled: FOG LP, HDLP-LOW, DRL, HDLP-HI

I used this clever little device to replace the BriteBox controller i installed ten years earlier. This little board allowed me to completely remove the excess wiring, relay box, and connectors the BriteBox required. SUPER simple to install and so far seems to be rugged enough to cope with the hundreds of rough dirt roads i travel weekly. Must buy if you want that "all on" when you hit the high beams.
