Chevrolet Trax Headlight Bulb Size

Chevrolet Trax headlight bulbs utilize 9008, 9005, and H11 sizes depending on beam configuration and model year, with high beam applications requiring 9008 or 9005 bulb sizes and low beam applications accommodating 9008, 9005, or H11 bulb sizes. The replacement chart covers 2015 through 2021 production years with corresponding bulb size specifications.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The 9008 bulb is a dual-filament halogen type rated at 12V with a 65W high beam filament and a 55W low beam filament, using a P26t base. Its dual-filament design means a single 9008 bulb serves both high and low beam functions within one housing.
The 9005 bulb is a single-filament halogen type rated at 12V, 65W, with a P20d base. It follows the ANSI standard applicable in the US and Canada, and when used as a low beam it operates at the same wattage as when used as a high beam.
The H11 bulb is a single-filament halogen type rated at 12V, 55W, with a PGJ19-2 base. It follows the ECE standard used in Europe and worldwide, though it also carries approval for use in the US market.
The 9008 and 9005 bulbs share the same ANSI standardization framework but are not interchangeable. The 9008 uses a P26t base and carries two filaments, while the 9005 uses a P20d base and carries only one, making their physical and electrical configurations distinct.
On the Chevrolet Trax, the 9008 bulb appears exclusively in 2021 model year entries and only in configurations that exclude the Control Leveling System. In those 2021 trims, a single 9008 bulb covers both the high beam and low beam positions simultaneously.
The H11 bulb is the low beam fitment for the 2015-2016 model years across all configurations, and it continues as an option in 2017-2021 for vehicles without projector-type headlamps, making it the most consistently recurring low beam bulb across the specification range.
For 2017-2020, the low beam fitment depends on headlamp assembly type: vehicles with projector-type headlamps use the 9005, while those without use the H11. These two bulbs have different base types and wattage ratings and are not interchangeable with each other.
The 2021 model year carries the greatest number of fitment variations, with three distinct low beam bulb sizes listed across different trim and equipment configurations, requiring precise identification of the headlamp system before a replacement bulb is selected.
