This 2021 GMC Sierra 1500 AT4 was completed as a first responder POV build. It features an all Whelen warning light package, including an Inner Edge FST visor bar, LINSV2 under-mirror lights, T-Ion lights in the grille, as well as T-Ions on the rear spoiler and license plate. This build was equipped with DUO T-Ions on the rear license plate which act as warning lights as needed, but also double as additional area lighting to the rear when the vehicle is shifted into reverse. This vehicle was retrofitted with an OEM General Motors upfitter/auxiliary switch kit which is used to control the setup.
