2006 Tahoe Tail Light Bulbs
Open Tailgate Door
Loosen Phillips Head Screws
This automotive maintenance tutorial was specifically written to assist owners of the second generation (2000, 2001, 2002, 2003, 2004, 2005 & 2006) GM Chevrolet Tahoe SUV in changing a burnt out brake, rear turn signal or reverse bulb in the tail light housings.

Owners of other General Motors GMT800 series SUV or truck vehicles such as the Chevy Silverado, Suburban, Avalanche, GMC Yukon, Sierra, Hummer H2 and the Cadillac Escalade may also find these DIY instructions to be helpful.

Replacement bulbs with their part numbers are as follows: Brake # 3047K (you can also use # 3057 or 3157), Rear Turn Signal # 3157 and Reverse # 3157.

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

Turn Counterclockwise
Two Screws Removed
Pull Off Tail Light Housing
The first two steps are to open the tailgate door and then move to the side of the vehicle with the burnt out tail light bulb.

Remove the two screws on the inner edge of the tail light assembly by turning them counterclockwise with a Phillips head screwdriver.

Set the two screws aside in a safe place.

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

Turn Over Housing
1/4 Turn Counterclockwise
Pull Out Old Brake Bulb
Turn over the housing and rest it on the bumper to access the bulb sockets.

The Brake light bulb is located at the bottom of the assembly.

Rotate the grey bulb socket 1/4 turn counterclockwise before pulling it straight out of the housing.

Pull the old brake light bulb straight out of the socket and push in a new # 3047K bulb.

You can also use a # 3057 or 3157 bulb.

Push In New # 3157 Bulb
1/4 Turn Clockwise - Lock
Reverse Light Bulb Socket
Re-insert the socket in to the housing and rotate it 1/4 turn clockwise to secure it in place.

The Reverse bulb socket is located at the center of the housing.

Rotate the socket 1/4 turn counterclockwise before pulling it straight out.


Pull Out Old Bulb
Push In New # 3157 Bulb
1/4 Turn Clockwise - Lock
Pull the old 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.

1/4 Turn Counterclockwise
Turn Signal Bulb Socket
Pull Out Old Bulb
The Rear Turn Signal bulb socket is located at the top of the housing.

Rotate the bulb socket 1/4 turn counterclockwise before pulling it straight out of the assembly.

Push a new # 3157 bulb straight in to the socket.

1/4 Turn Clockwise - Lock
Line Up Pegs & Holes
Push On Tail Light Housing
Re-insert the socket in to the housing and rotate it 1/4 turn clockwise to secure it in place.

Line up the two plastic pegs or "spikes" on the back side of the housing with their corresponding holes in the metal body panel.

Carefully push the tail light housing on to the rear corner of the vehicle.

Replace Phillips Head Screws
Tighten Screws Clockwise
Test New Tail Light Bulbs
Tighten the two Phillips head screws by turning them clockwise until they are snug.

Try to avoid over tightening the screws to prevent from cracking the plastic tail light assembly.

Test the new tail light bulbs by having someone step on the brake pedal, activate the hazard signals and place the transmission in reverse.

Be sure to record the bulb change in your vehicle's service records.
