2018 Buick Enclave bulb fitment
The 2018 Buick Enclave uses LED lighting for both the low-beam and high-beam headlights. The supplied fitment data does not identify separate halogen bulb sizes or a projector versus non-projector headlight variation, so verify the original lamp assembly before ordering replacement parts.

- Exterior marker and running lights: Daytime running, parking, front side-marker, and rear side-marker lighting are LED.
