Stay safer, see further, and brighten your nighttime driving experience with our All Lights On device. The All Lights On allows your high-beams, low-beams, and fog lamps to all be on simultaneously to illuminate the roadway when your high beams are activated. When your high beams are not on, your low-beams and fog lamps will operate normally. The All Lights On module installs in less than 10 minutes and will fit the following range of vehicles equipped with factory installed fog lights: 2015 - 2020 Chevrolet Colorado and GMC Canyon 2007.5 - 2021 Chevrolet Silverado & GMC Sierra 1500/2500HD/3500HD 2007 - 2020 Chevrolet Tahoe & Suburban 2007 - 2020 GMC Yukon & Yukon XL 2007 - 2014 Cadillac Escalade 2007 - 2013 Chevrolet Avalanche 2008 - 2017 Buick Enclave 2009 - 2017 Chevrolet Traverse 2010 - 2016 GMC Terrain 2007 - 2010 Saturn Outlook 2010 - 2019 GM Equinox 2013 - 2016 Chevrolet Trax 2008 - 2013 Chevrolet Impala 2016 - 2019 Buick Envision
