For the 2008 Subaru Impreza, the high-beam headlight uses a 9005 bulb. Low-beam fitment depends on the trim: H11 is listed for the 2.5i, while the WRX STI uses a D2S low-beam bulb. Confirm the vehicle trim before ordering, since these low-beam applications are not interchangeable.

- Front turn signals and parking lights use 3457A on the 2.5i or 1157A on the WRX STI.
- Reverse lights use 7440 on the Wagon; 921 is also listed.
- Brake and tail lighting varies: the Sedan uses 7443R, while the 2.5i Wagon uses LED lighting.
- Rear turn signals use 7440A.
- Interior dome and map lights use DE3175.
Additional body-specific listings include 3457A or 1157A front side markers, 7443A or 168NA rear side markers, and 168 or 917 license-plate bulbs. The center stop light is listed as LED, with 7506 specified for the Sedan.
