This automotive "how-to" guide was specifically written to assist owners of the 2005, 2006, 2007, 2008, 2009 or 2010 Chevrolet Cobalt in replacing a burnt out license plate light bulb.

Owners of other similar GM vehicles such as the Cruze, Impala, Malibu, Sonic, Lumina, Buick LaCrosse, Regal, Verano, Enclave, GMC Acadia, Yukon, Pontiac Grand Prix, G6, G5, Grand Am, GTO, Vibe, Sunfire, Oldsmobile Alero, Aurora, and Cutlass may also find this DIY guide to be helpful.

A replacement license plate light bulb for the '05-'10 Cobalt is part # 194 from various manufacturers such as Sylvania, GE, PIAA and Eiko.

If you would like to have brighter license plate lights, install some compatible 194 LED bulbs.

The only tool needed to replace the bulb is a standard Phillips head screwdriver.

1/4 Turn Counter Clockwise
Remove Bulb Socket
Old # 194 Light Bulb
Remove the two Phillips head screws that secure the license plate light bulb housing to the trunk lid by turning them counter clockwise.

Once the the two screws are removed, you can pull out the entire housing from the underside of the trunk lid. To access the bulb, rotate the light grey socket 1/4 turn counter clockwise and pull it straight out of the housing.

Light Bulb Socket
Push In New # 194 Bulb
Insert Bulb In Housing
Pull the old # 194 light bulb straight out of the socket and push in a new one.

If necessary, you an also use any other miniature wedge base bulbs such as the number 158, 168, W5W, 2825 or a compatible LED unit.

Insert the bulb back into the housing and rotate the socket 1/4 turn clockwise to secure it in place.


1/4 Turn Clockwise

Then re-insert the bulb housing back into the trunk lid and thread in the two Phillips head screws a few turns by hand.
