GM Impala Headlight
Open Hood

This automotive how-to guide was specifically written to assist owners of the 9th generation (2006 to 2011) Chevrolet Impala in replacing the low beam, high beam or parking / turn signal light bulbs in the headlight assemblies.

Owners of other similar W-Body or "W" platform vehicles such as the Lumina, Monte Carlo, Buick Regal, Century, LaCrosse, Allure, Pontiac Grand Prix, and Oldsmobile Cutlass Supreme may also find this guide to be useful.

The headlight assembly of a Chevy Impala contains the following bulbs: Low Beam bulb part # H11, High Beam bulb part # H9, and Turn Signal / Parking Light bulb part # 3157NA.

To remove the headlight assembly and access the bulbs, you'll need a 7mm socket and ratcheting wrench. A pair of needle nose pliers should also be able to remove the one 7mm screw.

7 MM Screw
White Plastic Clip
7mm Screw Removed
The first step is to open the hood of the car and move to the side of the vehicle with the burnt out headlight bulb. Locate the 7mm screw near the outer edge of the car and the white plastic retaining clip near the center of the vehicle. Remove the one screw with the 7mm socket and ratcheting wrench or needle nose pliers.

Next, pull the white plastic retaining clip on the headlight assembly straight up and out. Now that the 7mm screw and plastic clip have been removed, you should be able to pull the headlight assembly away from the front of the car. Gently turn the assembly upside down and rest it on top of the lip of the bumper. You may want to put a towel underneath the headlight to protect the paint on the bumper.

The low beam bulb is located in the middle of the headlight assembly. To access it, remove the large round dust cover seal by twisting it 1/4 turn counter clockwise.

Remove Socket & Bulb
Pull Out Amber Bulb
Bulb # 3157NA
To remove the amber colored turn signal bulb from the socket, pull it straight out. If it doesn't come out easily, try wiggling it while pulling it out. Replace it with a new # 3157NA bulb by pushing it straight down into the socket. (The Sylvania website lists the # 4157NA bulb as the proper replacement for the 2010 Chevy Impala. Both the 3157NA & 4157NA should work. Insert the new bulb and socket back into the headlight assembly and rotate it 1/4 turn clockwise to secure it in place.

Once you have replaced the burnt out bulb(s), re-install the headlight assembly by lining up the metal point on the outer edge and the black plastic tab on the other side with the corresponding points on the car. Push them into place.
