2020 Buick Enclave bulb fitment starts with LED low-beam and high-beam headlights. The supplied data does not list a separate halogen option or a projector/non-projector distinction, so confirm the original lamp assembly before ordering replacement parts.
- Front turn signals use 7444NA bulbs.
- Reverse lights use 921 bulbs.
- License plate lighting may use either 168 or 917, depending on the installed lamp.
- Brake lights, the center stop light, daytime running lights, parking lights, front and rear side markers, tail lights, and rear turn signals are listed as LED.
- Map and trunk lights are also LED.
- Dome-light fitment includes 194 and 7441 options, so check the existing bulb or socket before purchasing.
No fog-light bulb fitment is listed in the supplied information. For LED assemblies, replacement may involve the complete lamp or an assembly-specific component rather than a conventional replaceable bulb.
