What Lighting System Does the 2018 Chevrolet Trax Have?
The 2018 Chevrolet Trax features an extensive lighting system with 12 bulb positions. It uses halogen technology with a single 9005 LED dual-filament bulb handling both low and high beams. The Trax has been available from 2013 to 2019, and the 2018 model falls in the late-generation years.
Can You Put LED Bulbs in a 2018 Chevrolet Trax?
Upgrading the 2018 Chevrolet Trax to LED headlights is straightforward since it uses a single 9005 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 9005 LED LED kit that specifically supports dual-filament operation to ensure both beams work correctly. For the fog lights, a H8 LED LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 2018 Chevrolet Trax
The 9005 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. On the 2018 Trax, you will likely encounter rubber dust covers behind the headlight housing. These pull off by hand or unscrew depending on the design. Allow about 15 to 20 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 H8 LED fog light socket.

Standard halogen headlights on the 2018 Chevrolet Trax 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 8 years old, the original bulbs on your Trax 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 2018 Chevrolet Trax?
The 9005 low beam bulb on the 2018 Chevrolet Trax is cross-compatible with HB3 bulbs. These share the same physical base and electrical connection, so they will fit the socket. However, 9005 is the recommended size because it is optimized for the wattage and beam pattern designed into your headlight housing. 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.
