Does a catalog match guarantee the bulb fits?

A designation match means the product is filed under that bulb number and technology. It does not prove the lamp, socket, or vehicle configuration. Check the bulb in the housing before ordering.

How do I verify the replacement?

Read the number on the bulb or the housing, confirm whether the headlights are halogen, HID, or LED, and match that designation. Position names that say “with halogen headlights” or “with LED headlights” are separate configurations.
