This automotive "how-to" guide was specifically written to assist owners of the 2009 to 2012 GM Chevrolet Traverse crossover SUV in replacing the low beam, high beam, front turn signal and front side marker light bulbs in the headlight assemblies.

Owners of other General Motors vehicles from GMC, Saturn, Buick, and Cadillac such as the Acadia, Terrain, Sierra, Yukon, Savana, Outlook, Verano, Regal, Lacrosse, Encore, Enclave, Spark, Sonic, Cruze, Malibu, Impala, Camaro, Equinox, Tahoe, Suburban, Colorado, Avalanche, Silverado, ATS, XTS, CTS, SRX, and Escalade may also find these DIY instructions to be helpful.

Replacement headlight bulbs with their part numbers are as follows: Low Beam # H11, High Beam # 9005, Turn Signal # 4157NA, and Side Marker # 194NA.

The only tool needed to access any of the bulbs is a Torx T20 star bit screwdriver.

Pull Back Wheel Well Liner
The first step is to turn the wheels all the way to the opposite side of the burnt out headlight bulb.

This will give you some more room to work since all of the bulbs are accessed through the wheel well liner or "splash guard".

Use a Torx T20 star bit screwdriver to remove at least two of the screws that hold the front part of the wheel well liner in place.
