G6 Tail Light Housing
Inside Corner of Trunk
Pull Off Rubber Grommet
This automotive "how-to" guide was specifically written to assist owners of the 2006 Pontiac G6 GT in replacing the brake light bulb and reverse (back up) light bulb in the tail light housing.

Owners of other Pontiac G6 vehicles from 2005, 2006, 2007, 2008, 2009 & 2010 in base V6, SE, GT, and GTP trim levels featuring the 2.4L, 3.5L, 3.6L and 3.9L engines should also find this guide to be useful.

The Pontiac G6 tail light assembly contains two bulbs and their replacement part numbers from Sylvania and other manufacturers are as follows: Sylvania 3157 or 3157K Brake Light, and Sylvania 921LF or 921 Reverse Light.

(The online Sylvania bulb guide lists part # 3057 for the brake/signal/parking bulb.)

To replace one or more of the tail light bulbs on a 2005, 2006, 2007, 2008, 2009 and 2010 Pontiac G6 requires a 10mm socket with a 1/4" drive ratchet and a small flat head screwdriver.

3 Rubber Covers Removed
10mm Bolts Exposed
10mm Tail Light Nut
The first step is to pop the trunk and locate the three rubber grommets at the corner of the trunk.

These rubber grommets cover the one 10mm bolt and two 10mm nuts that secure the Pontiac G6 tail light to the rest of the car.

10mm Socket & Ratchet
One Bolt & Two Nuts
Tail Light Housing Removed
The grommets can be removed with just your finger nails or a small flathead screwdriver.

Once they are removed, use a 10mm socket attached to a ratcheting wrench to turn the one bolt and two 10mm nuts counter clockwise until you can spin them off with your fingers.

Try not to lose them behind the trunk's bodywork. Set them aside in a safe place.

1/4 Turn Counter Clockwise
Reverse (Back Up) Light
To remove the brake/parking/signal light bulb or the reverse (back up) bulb, just turn the socket a 1/4 turn counter clockwise and pull the connector/socket/bulb straight out from the tail light housing.

To remove the 3157 brake bulb or the 921 reverse bulb from their sockets, pull them straight out.

If you have any trouble, try wiggling while you pull them out.

Once you have the new bulb(s) inserted into the socket, test them by turning on the lights, hazard lights and have someone step on the brakes.

Re-install the bulb & socket by inserting them into the housing and turning them a 1/4 turn clockwise.

To finish the job, gently line up the tail light housing and push it into the cavity on the rear corner of the car.

Get the two 10mm nuts and one 10mm bolt started by using your fingers and them tighten them with the 10mm socket & wrench.

Replace the 3 rubber nut/bolt covers and you're done!
