Technical details and sources

Confirm the installed bulb, connector, housing, and factory system before ordering.

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.
