For the 2005 Subaru Forester, the low-beam and high-beam headlights both use a 9003 bulb. This shared fitment simplifies replacement, but verify the original bulb before ordering if the vehicle has been modified.
Front fog lights are listed with two possible fitments: H3 and H3C. Compare the existing fog-light bulb and socket to determine which option applies. The front and rear turn signals use amber 7440A bulbs, while the brake and tail lights use red 7443R bulbs.
Other notable exterior fitments include 921 reverse-light bulbs, 912 for the center stop light, and 168NA for the front side markers. Parking and license-plate lights may use either 168 or 917 bulbs, so compare the original bulb. Interior lighting includes DE3175 bulbs for both the dome and map lights. The trunk light also accepts either 168 or 917. For the ash light, the listed options are 2721 or 74; compare the original before purchasing.
