Description Factory-style headlights are identical to the original unit in every way— the same quality and the same method of installation. And every headlight assembly undergoes strict testing before it leaves the factory. All wiring is rigorously tested to ensure the light is completely functional. A new pair of headlights can provide you with up to 50% more illumination than dull, yellowed, sandblasted, broken, or scratched headlights. Note: Professional installation would be highly recommended. Fitment For 2007-2013 Chevrolet Avalanche Pickup Truck (1500 ONLY) For 2007-2014 Chevrolet Suburban For 2007-2014 Chevrolet TahoeNote?
