Don't even think about buying this product. After owning them for less than 3 months the one Lamp developed condensation in the lens and they refused to take it back cause it only had a lousy Warranty. I will be posting this on Facebook also. Don't buy this product.Looks great on the 2014 GMC Sierra 3500I was disappointed they didn’t fit exactly as OE, look nice, but the screws that hold the high beams are not the same size and the bracket that holds them in is cheap and I had to leave 1 off off on both sides and the driver side wouldn’t lock in correctly . I wish I had read this review before I bought them, bc I would have bought something else. Also ther are no instructions for the led light which is no problem it’s just black a white wire.Lights looked great until one, the drivers side, started turning a yellowish color and appears to have scratches or cracks on the inside. Passenger light is fine.Would not recommend since they were no help in replacement because it was after my 90 days period.Have these professionally installed save you major headaches I thought they were a little expensive but they are very niceThe headlights were a good value for the money. They are a good fit and look nice on the truck.They fit to a tee!!!!!Installed a week ago and they fogged up from the inside
