This automotive maintenance tutorial was specifically written to assist owners of the third generation (2007, 2008, 2009, 2010, 2011, 2012, 2013 & 2014) Chevrolet Tahoe in changing a burnt out brake, rear turn signal or reverse bulb in the tail light assemblies.

Owners of related General Motors vehicles with similar tail light housings such as the Suburban, Avalanche, GMC Yukon, Yukon XL, Yukon Denali, Sierra, Cadillac Escalade and Hummer H2 may also find these DIY instructions to be helpful.

Replacement bulbs with their part numbers are as follows: Brake # 3057 or 3057K, Rear Turn Signal # 3057 or 3057K and Reverse # 7441 or 7440.

The only tool required to replace the bulbs is a standard Phillips head screwdriver.

Pull Off Tail Light Housing
The first two steps are to open the rear cargo tail gate and then move to the side of the vehicle with the burnt out tail light bulb.

Loosen the two screws on the inner edge of the tail light housing that were hidden behind the tail gate by turning them counter clockwise with the Phillips head screwdriver.

Set the two screws aside in a safe place.

The housing is still held in place by two pegs or "spikes" on the back side near the outer edge that act as friction fasteners inserted in to grommets.

Pull the tail light housing straight off the rear corner of the SUV.

If you have trouble removing the tail light assembly from the rear of the SUV, carefully insert a small flathead screwdriver or a plastic automotive panel removal tool in between the housing and the painted metal quarter panel on the side of the vehicle.

Gently pry to loosen the two friction fasteners.

Then try gently wiggling the housing while pulling it straight off the vehicle.

To prevent from scratching the plastic tail light lens or the painted bumper, place a towel in between the two surfaces.

Turn over the tail light housing and rest it on the bumper.

The Rear Turn Signal light bulb socket is located at the bottom of the housing.
