This automotive maintenance tutorial was specifically written to assist owners of the second generation (2015, 2016, 2017, 2018, 2019 and probably also the updated 2020 model year) GM Chevrolet Colorado truck in changing a burnt out dome (also known as the "room lamps" or rear passenger reading) light bulb in the housing attached to the headliner above the second row of seats.

Owners of other General Motors vehicles from Chevrolet, GMC, Cadillac, Buick and Holden such as the Trax, Equinox, Traverse, Blazer, Tahoe, Suburban, Sonic, Cruze, Trailblazer, Spark, Malibu, Impala, Volt, Bolt, Corvette, Camaro, Silverado, Express, Regal, LaCrosse, Cascada, Encore, Enclave, Envision, Canyon, Sierra, Terrain, Acadia, Yukon, XT4, XT5, XT6, Escalade, CT5, CTS, XTS, CT6, ATS, Astra and Commodore may also find these DIY instructions to be helpful.

The compatible replacement miniature wedge base light bulb part number is 2825 (also known as W5W).

If you would like to have brighter dome lights, install some 2825 LED bulbs.

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

To prevent from scratching the plastic surfaces, either use a plastic pry bar tool or cover the tip of your screwdriver with a thin micro fiber cloth.

Insert the screwdriver or small plastic pry bar tool in between the lens cover and the headliner or the plastic light housing.

Pull Out Old Light Bulb
Gently pry the lens cover out of the light housing.

You may need to re-insert the screwdriver or plastic pry bar tool into several locations around the lens cover to fully remove it.

The lens cover is held in place by a variety of barbed plastic tabs and two "C" shaped retaining clips.

Set the lens cover aside in a safe place.

If the old light bulbs were recently turned on, it might still be hot enough to burn your fingers. Please be careful when you remove it.

Pull the old light bulb straight out of the socket.

Gently Pop In Lens Cover
I recommend testing the new light bulbs before re-installing the lens cover.

If you installed LED bulbs and they don't work, try removing them from the sockets, rotating them 180 degrees and pushing them back into the sockets.

Some LED bulbs only work when the "+" positive and "-" negative electrical contacts are in the correct orientation.

Line up the lens cover with the light housing.

The "C" shaped retaining clips should be situated closer to the front of the truck.

Gently snap the lens cover back into place.

To test the new light bulbs, press the "On/Off" switches.

Be sure to record the bulb change in your vehicle's service records.
