The Caprice Side Marker Light is specifically made for the 2011-2012 Chevy Caprice. This side marker light replaces the factory side marker on the vehicle. Since they replace the existing side marker there is no drilling, measuring, or cutting. Simply pop out the factory marker and replace with the Code3 Side Marker. The light is available in 3 different lens covers, red blue, and clear, and 10 different LED colors, red, blue, white, amber, red/blue, red/white, red/amber, blue/amber, blue/white, and amber/white. Each light has 3 T-Rex lightheads to increase visibility at intersections. Both side markers are included; one for the passenger side and one for the driver side. Each side can have a different set up for the lights and cover on the side marker. With GM standard wire and cable connectors included you can tie into the wiring harness or the vehicle.
