Owners of other General Motors vehicles with similar tail light housings such as the Spark, Cruze, Malibu, Impala, Traverse, Tahoe, GMC Terrain, Acadia, Yukon, Buick Verano, Regal, LaCrosse, Encore, Enclave and Holden Barina may also find these DIY instructions to be helpful.

Replacement bulbs with their part numbers are as follows: Brake # 7443, Rear Turn Signal # 4157NA or 4157A, Reverse # 3157 and Rear Side Marker # 194.

The only tool needed to change any of the bulbs is a standard Phillips head screwdriver.

Then locate the two screws along the inner edge of the tail light housing that were covered by the trunk lid.

Remove the screws by turning them counter clockwise with a Phillips head screwdriver and set them aside in a safe place.

The housing is still held in place by two metal friction fasteners on the rear of the housing at the outer edge.

If you have trouble removing the tail light, try gently wiggling the housing while continuing to pull it.

To prevent the plastic lens or the painted bumper from getting scratched, place a towel in between the two surfaces.

Turn the housing over and rest it on the bumper.

The black plastic brake light bulb socket is located at the top of the housing.

Rotate the socket 1/4 turn counter clockwise and pull it straight out of the housing.

Re-insert the socket in to the housing and rotate it 1/4 turn clockwise to lock it in place.

Rotate the socket 1/4 turn counter clockwise and pull it straight out of the housing.

Pull the old bulb straight out of the socket and push a new amber colored # 4157A or 4157NA bulb.

The green plastic reverse bulb socket is located at the bottom of the tail light housing.

Pull the old reverse bulb straight out of the socket and push in a new # 3157 bulb.

Re-insert the socket in to the housing and rotate it 1/4 turn clockwise to secure it in place.

Rotate the side marker socket 1/4 turn counter clockwise to remove it, pull out the old bulb, push in a new # 194 bulb, re-insert the socket and rotate it 1/4 turn clockwise to secure it in place.

You can also use any other miniature wedge base bulb such as the # 168, W5W, 2825 or a compatible LED unit.

Line up the two metal pegs or "spikes" on the outer rear edge of the tail light assembly with their corresponding grommets on the corner of the vehicle.

Gently push the tail light housing back in to place.

Tighten the screws by turning them clockwise with the Phillips head screwdriver until they are snug.

Do not over tighten the screws to avoid cracking the plastic tail light housing.

Test the new bulbs by having someone turn on the parking lights, step on the brake pedal, activate the hazard signals and place the transmission in reverse (with the engine off for safety).
