The Fleece Performance All Lights On module fits the 2020-2023 GMC Sierra 3500HD and runs your high-beams, low-beams, and fog lamps at the same time when high beams are active.
Product Overview
The All Lights On is a plug-in module that overrides the factory headlight logic on your Sierra 3500HD. When you flip on the high beams, the low-beams and fog lamps stay lit for maximum forward and peripheral illumination.
With high beams off, the low-beams and fog lamps operate normally. Your truck must be equipped with factory fog lights for this device to function.
