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 a 1/4" drive ratchet.

A pair of needle nose pliers should also be able to remove the one 7mm screw.

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.

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.

To access it, remove the large round dust cover seal by twisting it 1/4 turn counter clockwise.

Pull it straight out from the headlight assembly and pry up on the yellow retaining clip to separate it from the power connector.

Turn it 1/4 turn clockwise to secure it.

Remove it by twisting it 1/4 turn counter clockwise and pull it off the back of the headlight assembly.

Pry up the power connector's black plastic retaining clip to separate it from the base of the high beam bulb.

Rotate it 1/4 turn clockwise to secure it.

Replace the round black plastic dust cover and rotate it 1/4 turn clockwise to lock it in place.

Turn the base 1/4 turn counter clockwise and 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.

Push them into place.

Check that all the headlight bulbs work by turning on the lights, turn signals, and high beams.
