SuperVisor TriCore is made for a custom fit into specific vehicle types. Since this lightbar is custom the lights do not shine into the driver's or passenger's eyes. The thin design keeps the car undercover until energized. TriCore technology is used when making the lights. Easy to install and no drilling required. The bar mounts underneath the visor using the visor mounts for the visor to keep it in place. The interior lightbar comes custom for the 2007+ Tahoe, 2007-2013 Silverado, 2007+ Suburban, 2007+ Expedition, 2012+ Police Interceptor Utility, 2013+ Durango, 2011+ F-150, and the 2007-2011+ Explorer.
