The Vision X Shocker Dual Action LED Light Bar uses VRT (Vector Reflector Technology) to shine long distance with a wide driving beam, while the lower Amber PLC (Photon Light Core Technology) penetrates the dusty/foggy night by reducing shadows and white-out. The proper Amber lighting color and wide-elliptical shaped beam reduces eye strain. Patent Pending All Shocker LED Light Bars are backed by our lifetime warranty.
