Anyone know how to change the daytime running bulbs in a 01' Silverado? Thanks in advance?

That's easy! Raise the hood, look above the headlights and you'll see two pins, probably 1/4" diameter. Remove both of these pins and the headlights and drl assemblies will pop right out the front.

Once you get the HEADLIGHT BODY out you have to go down further and get the TURNSIGNAL BODY out next as the '01 DRL's are in the TURNSIGNAL BODY. Twist and pull the light closest to the grille and you will have the DRL's out.

Good Luck
