What Lighting System Does the 2012 Chevrolet Colorado Have?
The 2012 Chevrolet Colorado features an extensive lighting system with 13 bulb positions. It uses halogen technology with 9006 LED low beams and 9005 LED high beams in a dual-bulb configuration. The Colorado has been available from 2004 to 2019, and the 2012 model falls in the mid-generation years.
Can You Put LED Bulbs in a 2012 Chevrolet Colorado?
To upgrade the 2012 Chevrolet Colorado headlights to LED, you will need a 9006 LED LED kit for the low beams and a 9005 LED LED kit for the high beams. Start with the low beams since they are used most often and have the biggest impact on nighttime visibility. For the fog lights, a 9045 LED LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 2012 Chevrolet Colorado
The 9006 bulb uses a push-and-twist L-shaped bayonet lock. To remove the old bulb, disconnect the wiring harness first, then twist the bulb counter-clockwise and pull it out. Older model years like the 2012 Colorado typically offer easy access to the headlight bulbs from behind the headlight assembly under the hood. Most owners can complete the swap in under 10 minutes per side. When installing the new bulb, avoid touching the glass with bare fingers. Skin oils create hot spots that shorten bulb life. Wear clean gloves or handle the bulb by its plastic base only. The fog lights are accessed from underneath the front bumper. You may need to remove a few plastic clips or screws from the fender liner to reach the 9045 LED fog light socket.

Shop Complete LED Kit for 2012 Chevrolet ColoradoHow Long Do 2012 Chevrolet Colorado Headlight Bulbs Last?
Standard halogen headlights on the 2012 Chevrolet Colorado have an expected lifespan of 500 to 1,000 hours, which works out to roughly 2 to 3 years of normal use. Signs of a failing halogen bulb include noticeably dimmer output, a yellowish tint compared to the other headlight, or intermittent flickering. At 14 years old, the original bulbs on your Colorado are likely overdue for replacement. Even if they still illuminate, reduced brightness significantly impacts nighttime safety. When one headlight burns out, replace both sides at the same time. Bulbs from the same batch age at similar rates, and mismatched brightness is distracting to oncoming drivers.
What Bulbs Are Compatible with the 2012 Chevrolet Colorado?
The 9006 low beam bulb on the 2012 Chevrolet Colorado is cross-compatible with HB4 bulbs. These share the same physical base and electrical connection, so they will fit the socket. However, 9006 is the recommended size because it is optimized for the wattage and beam pattern designed into your headlight housing. For the high beams, the 9005 is interchangeable with HB3. Using the wrong bulb size can cause improper beam patterns that reduce your visibility and blind other drivers. It can also cause overheating inside the headlight housing, potentially warping the plastic lens or reflector. Always verify the bulb number before purchasing.
