Keep the factory system

The main headlights use integrated factory LEDs, not conventional replaceable bulbs. Diagnose aim, wiring, modules, moisture, and the assembly before ordering service parts by VIN.

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.
