2012 Traverse Tail Light
Open Cargo Liftgate
Pry Out Screw Covers
This automotive "how-to" guide was specifically written to assist owners of the 2009, 2010, 2011, 2012, 2013, 2014, 2015 & 2016 GM Chevrolet Traverse crossover SUV in replacing the combination brake and turn signal, rear side marker, or the reverse bulb in the tail light assemblies.

Owners of other General Motors crossovers, SUVs, minivans or trucks such as the Chevy Equinox, Tahoe, Suburban, Colorado, Avalanche, Silverado, GMC Canyon, Sierra, Acadia, Yukon, Denali, Savana, Pontiac Aztek, Torrent, Saturn Outlook, Buick Encore, and Enclave may also find these DIY instructions to be helpful.

Replacement bulbs and their part numbers are as follows: Brake/Turn Signal # 7443, Rear Side Marker # 194, and Reverse (Back-Up) Light # 912.

The reverse light bulb for the 2013, 2014, 2015 & 2016 model years is part number 921.

The tools needed to access the tail light bulbs include a small flathead screwdriver and a 7mm socket with ratcheting wrench.

Screw Covers Removed

Upper 7mm Screw Removed
Move to the rear of the vehicle and open the cargo tailgate door.

Locate the two small round plastic screw covers on the inside edge of the tail light housing. Pry out the screw covers with the small flathead screwdriver.

Remove the upper and lower tail light screws with a 7mm socket and ratcheting wrench.

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

The combination brake and turn signal dual filament light bulb is the larger of the two sockets.

Pull the old # 7443 bulb straight out of the socket and push in a new one.

Test the new brake light / turn signal light bulb by having someone step on the brake pedal and activate the hazard signals.
