For the 2002 Subaru Legacy, headlight fitment varies by lamp assembly. The low beam may use a 9007 or H1 bulb, while the high beam may use a 9005 or 9007. Check the bulb currently installed and compare the headlight housing before ordering, since the supplied options do not identify a single bulb for every vehicle.
Fog lights use either H3 or H3C. Front turn signals require comparing the original bulb, with 1156A and 1157A listed as the available options.
Several rear-light bulbs depend on body style:
- Sedan: reverse and brake/tail lights use 3156 and 3157R, respectively; the rear turn signal uses 3157.
- Wagon: reverse and brake/tail lights use 1156 and 1157R, respectively; the rear turn signal uses 7440.
The center stop light uses 921, with 912 also listed for the wagon. License plate lighting may use 168 or 917. Dome and map lights use DE3175, while the trunk light may use 2825, 98, or 912 on an L wagon.
