This automotive "how-to" guide was specifically written to assist owners of the 2nd generation (2007, 2008, 2009, 2010, 2011, 2012 & 2013) Chevrolet Silverado 1500 in replacing a burnt out high mount stop light or cargo bed light bulb.

Owners of other General Motors vehicles such as the GMC Sierra, Terrain, Acadia, Yukon, Savana, Chevy Colorado, Avalanche, Express, Equinox, Traverse, Tahoe, Suburban, Spark, Sonic, Cruze, Volt, Malibu, Impala, SS, Camaro, Corvette, Verano, Regal, LaCrosse, Encore, and Enclave may also find these DIY instructions to be helpful.

A replacement bulb is part # 912 from manufacturers such as Sylvania, Eiko and GE.

You may also choose to install brighter LED units.

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

Remove 2nd Phillips Screw
Two Screws Removed
Pull Out Light Housing
The first step is to climb in to the cargo bed of your truck with a Phillips head screwdriver.

Then remove the two Phillips head screws holding the 3rd brake light and cargo area light bulbs housing in place by turning them counter clockwise. Set the two screws aside in a safe place.

Gently pull the light housing away from the top of the passenger cabin.

Turn Over Assembly
1/4 Turn Counter Clockwise
Pull Socket Out
Turn the light housing over. The two outer sockets contain the cargo area light bulbs and the two inner sockets contain the high mount 3rd brake light bulbs.

Grasp the socket that contains the burnt out bulb with your thumb and forefinger before rotating it 1/4 turn counter clockwise.

Pull the socket straight out of the housing.


Pull Out Old # 912 Bulb
1/4 Turn Clockwise
Unplug Power Connector
Pull the old light bulb straight out of the socket and push in a new # 912 miniature wedge base bulb.

If you have trouble removing a bulb socket, give yourself more room to work by disconnecting the power plug.

Re-insert the two Phillips head screws.

Tighten Two Screws

Test New Brake Lights
Tighten the two screws with the Phillips head screwdriver until they are snug. Do not over tighten the screws to avoid cracking the plastic housing.

Test the new third brake light bulbs by having someone step on the brake pedal.
