For the 2007 Mazda Mazda6, the high-beam headlight uses an H1 bulb. Low-beam fitment depends on the headlight assembly: models with halogen headlights use H1, while models with HID headlights use D2S. Confirm the headlight type before ordering, since these low-beam bulbs are not interchangeable.
The fog lights use H11 LED bulbs. Other notable exterior fitments include a 2357A front turn signal, 7443R brake and tail lights, a 7440A rear turn signal, and a 921 reverse light.
- The center stop light may use 921 or 7440; compare the original bulb before replacing it.
- Parking light fitment may be 2825 or 2357A; compare the original bulb.
- License plate, front side-marker, courtesy, dome, and map lights use 2825 bulbs.
