What Lighting System Does the 2004 Chevrolet Colorado Have?

The 2004 Chevrolet Colorado features an extensive lighting system with 12 bulb positions. It uses halogen technology with a single H6054 LED dual-filament bulb handling both low and high beams. The Colorado has been available from 2004 to 2019, and the 2004 model falls in the early-generation years.

Can You Put LED Bulbs in a 2004 Chevrolet Colorado?

Upgrading the 2004 Chevrolet Colorado to LED headlights is straightforward since it uses a single H6054 LED dual-filament bulb for both low and high beams. You only need one pair of LED bulbs to upgrade both functions. Look for a H6054 LED LED kit that specifically supports dual-filament operation to ensure both beams work correctly. 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 2004 Chevrolet Colorado

To remove the headlight bulb, disconnect the wiring harness, then twist the bulb counter-clockwise and pull it straight out of the housing. Older model years like the 2004 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.

How Long Do 2004 Chevrolet Colorado Headlight Bulbs Last?

Standard halogen headlights on the 2004 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 22 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 2004 Chevrolet Colorado?

The H6054 low beam bulb on the 2004 Chevrolet Colorado is a specific fitment. There are no widely recognized cross-compatible alternatives, so make sure to purchase the exact H6054 size. 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.

LED bulbs used off-road or in auxiliary lights are legal everywhere. For on-road headlight use, legality varies by state. Many states allow LED retrofits as long as the beam pattern meets DOT standards. For the best legal compliance, choose a DOT-approved H6054 LED LED kit that is designed as a direct replacement and produces a proper cutoff pattern without excessive glare.

A pair of halogen H6054 LED bulbs costs $15 to $40, while LED conversion kits run $25 to $60 per pair. If you have a shop do the work, expect an additional $20 to $50 in labor per bulb. Replacing them yourself at home saves the labor cost and usually takes under 30 minutes.

Halogen bulbs produce a warm yellow light (around 3200K), last 500 to 1000 hours, and draw more power. LED bulbs emit a brighter white light (5000-6000K), last 25,000+ hours, and use less energy. LED upgrades for the H6054 LED position are available as direct plug-and-play replacements.
