How to Change a Cornering Lamp in a 2002 Buick Regal

by Robert Moore

    In the early 1970's, GM set out to create one of its first personal luxury cars; three years later, Buick released its seminal Regal. GM's general focus was to provide the driver with as many creature comforts as possible. However, later designs of the Regal focused more on a comfortable ride and a sporty drive. This luxury line continued until June of 2004 when the last Regal rolled off of the assembly line. The headlight assemblies on Regals built from 1997 to 2004 secure to the car using but two plastic clips, so you'll find replacing the turn signal or headlight bulbs are a breeze.

    Items you will need

    • No. 3157NA bulb
    Step 1

    Open the hood. Look between the headlight assembly and the radiator core support and find the two plastic retainers. They have flat tops, and are either black or white. Apply light, inward pressure on the headlight assembly, then pull upward on both tabs and remove them.

    Step 2

    Pull out on the headlight assembly. Lift the locking arm and separate the wiring harness from the headlight assembly. Remove the headlight assembly from the car. Pull the rubber cover for the turn signal bulb off the headlight assembly.

    Step 3

    Rotate the bulb socket counterclockwise, then pull it out of the headlight assembly. Squeeze the locking arms on both sides of the socket, while you pull the bulb out of the socket. Install a new No. 3157NA bulb into the socket and push it so that both locking arms grip the tabs on the side of the bulb's base. Insert the socket into the headlight assembly and turn it clockwise to lock it in place.

    Step 4

    Push the rubber cover onto the hole for the turn signal bulb. Connect the wiring harness to the headlight assembly, then push the assembly into place. Install the locking tabs and push downward on them to lock the headlight in place. Shut the hood.

    Tip

    • Remove the headlight assembly in the same fashion to replace the headlight bulbs.
