For the 2018 Chevrolet Colorado, the low-beam headlights use H11 bulbs, while the high-beam headlights use 9005 bulbs. The supplied fitment data does not identify separate bulb options by projector or non-projector headlight design, so these are the listed headlight applications for this model year.
The fog lights use 5202 LED bulbs. Exterior lighting includes 7444NA bulbs for the front turn signals and parking lights, while the rear turn signals use 7443 bulbs. The brake and tail lights use 7443R bulbs, and the rear side markers use 7443A bulbs.
- Reverse lights, center stop light, and trunk light: 921
- License plate and front side-marker applications: 2825 or 98
- Vanity light: 6612F
Check the position and bulb designation before ordering, especially where the fitment data lists more than one bulb option for the same lighting area.
