A headlight (headlamp) is a lamp attached to the front of a vehicle to light the road ahead. Headlight performance has steadily improved throughout the automobile age, spurred by the great disparity between daytime and nighttime traffic fatalities. Headlights are one of the most important components of your vehicle; they allow you to see the road in front of you clearly during the night and in any bad weather that may arise. Our headlights upgrade the face of your vehicle with clear style and extreme range.Package Included:1 X Pair of Headlights (Left & Right)1 X Pair of Turn Signal Running Lights (Left & Right)1 X 1/4" Drive Ratchet1 X 2" 1/4" Drive Extension1 X 3 1/4" Drive Extension1 X Bit Drive6-Piece Sockets : 7mm, 8mm, 9mm, 10mm, 11mm, 12mm 6-Piece 6-Point Star Torx Sockets : T10, T15, T25, T30, T35 2-Piece Philips & Standard Screw Driver Bits Trim Removal ToolBit extensionThis product is compatible with:99-07 GMC Sierra 150001-07 GMC Sierra 1500 HD99-04 GMC Sierra 250001-07 GMC Sierra 2500 HD01-07 GMC Sierra 3500HD99-06 GMC Yukon00-06 GMC Yukon XL 150000-06 GMC Yukon XL 2500Does NOT Fit All Denali Trims.
