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. Takedown lights can be adjusted to the proper angles and can be wired to an external flasher. They are easy to install and drilling is not required. The bar mounts underneath the visor, using the visor mounts to keep it in place. The interior lightbar comes custom for the 2006-2011 Charger, 2012+ Police Interceptor Sedan, 2001+ Caprice, 2006-2013 Impala, 2014+ Impala Limited, 2004-2011 Crown Vic.
