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 license plate light bulb located in the rear bumper cover.

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 194 (3.8 Watts).

Earlier Colorado models may be equipped with the 2825 bulb (5 Watts) which is also known as the W5W.

If you would like to have brighter license plate lights that will also last a lot longer before burning out, install some 194 LED or 2825 LED bulbs.

No tools are required to access and replace the bulbs.

To access the driver and passenger side license plate light bulb sockets, slide under the rear bumper of the truck.

Rotate the black and grey plastic of the bulb socket 1/4 turn in the counterclockwise direction before pulling it straight out of the housing.

Carefully pull the old light bulb straight out of the socket.

If you have trouble removing the old bulb due to rust or debris, put on some gloves and try gently wiggling it back and forth while pulling it straight out.

Avoid using excessive pressure on the old bulb to prevent from having it break and cut your fingers.

The OEM light bulb in this 2019 Colorado LT was marked as part number 194 (3.8 Watts).

Sylvania lists the compatible replacement part number as being the slightly brighter 2825 (5 Watts) bulb.

Push the new light bulb straight into the socket.

Clean off the new bulb with a paper towel or a micro fiber cloth.

If there is any grease or oil on the new bulb, it may cause a hot spot and lead to the bulb failing prematurely.

If you would like to have brighter license plate lights, install some compatible replacement 194 LED or 2825 LED bulbs.

Re-insert the bulb socket into the housing and rotate it 1/4 turn in the clockwise direction.

Make sure that the socket is securely in place.

New Light Bulb Installed
To test the new license plate light bulbs, turn on the parking lights or headlights.

You could also press the "Unlock" button on the key fob to activate the exterior lights.

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

Tip - If you installed LED bulbs and they don't work, try removing the bulbs from the sockets, rotate them 180 degrees and re-install them into the sockets. Some LED bulbs are "polarized" and will only work when the "+" positive and "-" negative electrical contacts are in the correct orientation.
