How to Replace the Daytime Running Lights on a 2002 Chevy Silverado

by Chris Gilliland Google

    In the early days of automobile history, cars and trucks simply made do with headlights, brake lights and turn signals. The 2002 Chevy Silverado, like many other modern vehicles, is equipped with a secondary lighting system that is active during the day to alert other drivers of the truck's location on the road. These daytime running lights can and will fail over time. They are simple enough to replace, but complete DRL failure can be caused by more than just bad bulbs. The relay that controls the DRL system can also fail at an inopportune moment. This relay, however, can also be replaced with little effort.

    Items you will need

    • No. 4114 bulbs
    • Shop towel
    • DRL relay

    DRL Bulb Replacement

    Step 1

    Open the hood and support it with the hood prop rod. Rotate the L-shaped retaining pin at the top of the headlight assembly out of the groove cut into the Silverado's chassis, then pull up on the pin to remove it.

    Step 2

    Pull the headlight assembly toward you until you can lift it out of place. Run your finger along the outer edge of the headlight and find the tab on the side of turn signal and DRL lens. Lift the tab and pull the lens away from the headlight assembly. Grasp the rear of the DRL socket on the back of the headlight assembly, nearest the engine. Twist the socket counterclockwise and pull it out of the headlight. Pull the DRL bulb out of its socket.

    Step 3

    Hold a new No. 4114 bulb with a shop towel and push it into its socket. Push the DRL socket into the headlight and twist it clockwise until it locks into place. Hook the turn signal lens over the inner side of the headlight assembly, then push the lens into place.

    Step 4

    Hook the bottom of the headlight assembly against the radiator support, then push the assembly into place. Slide the retaining pin into place, then rotate the pin into its mounting groove.

    DRL Relay Replacement

    Step 1

    Open the hood and lift the plastic cover off of the electrical center and fuse box -- the fuse box is located along the right side of the engine compartment, behind the battery.

    Step 2

    Pull the DRL relay -- the relay in the center of the fuse box, between the fuel pump relay and the air-conditioning relay -- out of the electrical center.

    Step 3

    Plug a new relay into the now-vacant spot in the electrical center. Push the cover into place over the electrical center and lower the hood.


    • Avoid touching the DRL bulb with your bare skin. The oils that are naturally present on human skin can cause premature bulb failure.
