Upgrade any Reverse Hitch Bar Light kit with a quick-install of the Hitch Bar Emergency Add-On Light plate. Simply unscrew your main 7-inch flush mount light, slide in the Race Sport Lighting Emergency plate, and screw the light back in. It’s that simple to upgrade and add your rear Amber/White Wig Wag Strobe Lights. Quick easy upgrade that is plug-and-play directly to the 2nd output on our Hitch Bar 2-Output harnesses.
