GM “All Lights On” High-Beam Module

Classic 2003-2007 GM pickups are common among work trucks. What is also common is those models leave a lot to be desired with the headlights as the high-beams are separate from the low-beams.

All Lights On Module

An easy way to greatly improve night driving is a five-minute upgrade inside the underhood fuse box.

Simply install the Fleece Performance Engineering GM All Lights On Module to allow your work truck’s 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 flip on the high-beams.

When the high-beams are NOT turned on, your work truck’s low-beams and fog lights will still function normally.

Add the supplied spade terminal to provide a signal ground when the high-beams are turned on to allow control an accessory relay to other auxiliary lights with the high-beam switch.
