2016 LaCrosse Courtesy Step Light
Gently Pry Out Light Housing
This automotive maintenance tutorial was specifically written to assist owners of the second generation (2010, 2011, 2012, 2013, 2014, 2015 & 2016) GM Buick LaCrosse sedan in changing a burnt out courtesy step light bulb located in the bottom of the plastic interior door panels.

Owners of other General Motors vehicles such as the Chevrolet Impala, Monte Carlo, Malibu, Spark, Sonic, Cruze, Volt, SS, Camaro, Caprice, Corvette, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado, Buick Verano, Regal, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra, Terrain, Acadia, Yukon, Savana, Cadillac CT6, ATS-V, ATS, ELR, CTS, XTS, XT5, SRX, Escalade and Holden Commodore may also find these DIY instructions to be helpful.

A replacement miniature wedge base bulb is part number 2825 from various manufacturers such as Sylvania, GE, Eiko and PIAA. You can also use a brighter LED unit.

The only tool needed to access and replace the bulbs is a small flathead screwdriver or a plastic pry bar tool.

Pull Out Light Housing
Push Out Old Light Bulb
Insert the tip of a small flathead screwdriver or a plastic pry bar tool in to the notch on the rear edge of the light housing.

Gently pry out the light housing and remove it from the underside of the door panel.

Be careful when you remove the old light bulb. If it was recently turned on, it might still be hot enough to burn your fingers.

Carefully push the old light bulb out of the base of the socket with the screwdriver or pry bar tool.

Old Light Bulb Removed
Old 2825 (W5W) Bulb
The OEM bulb is a number 2825 (also known as the W5W).


Push In New 2825 Bulb
Re-Insert Wires First
Push a new # 2825 bulb straight in to the socket.

If necessary, you can also use any other miniature wedge base bulbs such as the # 168, 158, 194 or a compatible LED unit.

Gently Pop In Light Housing
Test New Light Bulb
Re-insert the wires in to the opening in the door panel.

Gently pop in the retaining clip on the rear edge of the light housing to secure it in place.

Test the new light bulb by pressing the "Unlock" button on the key fob to activate the interior lights.
