The Complete Guide for Upgrading 2005 GMC Sierra 1500 Headlights to LED morsunled.mybloghunch.com

Once you've selected your new LED assemblies, gather your tools: a 10mm socket, ratchet, Phillips screwdriver, trim panel removal tools (or a flathead screwdriver wrapped in tape), and electrical tape. Begin by disconnecting the negative battery terminal to prevent any electrical shorts. Open the hood and locate the three 10mm bolts securing each headlight assembly. The top two bolts are easily accessible, but the third inner bolt requires partially removing the front grille. Remove the Phillips screws along the top edge of the grille and the plastic push-pins in the radiator cover. Gently pull the top of the grille forward—you don't need to fully remove it, just flex it enough to access the inner bolt with your socket.
