Review on AUTOSAVER88 Yellow Halogen Fog Lights 880 - 12V 27W Lamp Compatible With Chevy Silverado 1999-2002, Suburban 2000-2006, And Chevy Tahoe 2000-2006 by Shane Black

Similar to OEM lights being replaced, no problems or differences encountered. Need to remove outer bumper braces only to gain enough access. Do not tighten lights or reinstall bumper until you aim the lights. Two 10mm bolts hold the lights in and each brace has 3, 15 mm bolts. Included instructions only pertain to new installation where you have to run wires. Pay attention to the way the spring loaded up/down aiming bolts are installed so that you assemble those correctly, and before you bolt the lights in the truck. Lights were shipped quickly, packaged properly, and the price was great.
