Best headlight upgrades
BulbFacts does not currently have a supported primary-headlight bulb size for this configuration, so no product is being recommended.

Bulb size needs confirmation. Choose or verify the installed factory headlight system before using a bulb size or product recommendation.
Technical details and sources
Fitment, factory-system research, and BulbFacts product tests remain separate evidence. A matching bulb size does not by itself make a conversion a vehicle-specific recommendation.
Each model year opens its own BulbFacts record. Bulb sizes and factory systems are not carried over from adjacent years.
Fitment note: Verify the installed bulb, connector, housing, and factory system before ordering. A bulb-size match is not automatically a conversion recommendation or proof of vehicle-specific testing.
