This page helps you find the right bulb sizes for the 2001 Subaru Legacy by lighting position, so you can match the correct part before you buy. Because trim and body style can change the setup, it is useful to check each lamp location separately instead of assuming every bulb is the same across the car.
For the 2001 Subaru Legacy, the bulb chart includes common exterior and interior positions such as headlights, parking lights, turn signals, brake lights, license plate lights, dome lights, map lights, and cargo area lights. Use the listings here to verify the correct bulb for your sedan or wagon and avoid mix-ups between similar-looking sockets and bulb types.
Fitment can vary by trim, lighting package, market, and body style, so always compare the bulb in the vehicle with the chart before ordering. If you are switching from halogen to LED, make sure the replacement is compatible with the socket, polarity, and available space, and remember that some aftermarket LED conversions may not perform the same as the original halogen bulb. For the best results, check the installed bulb number first, especially on shared positions where more than one bulb option appears on the same year page.
The low beam headlight bulb is listed as H1 for this model year. Some versions may also use a combined high/low setup with 9007, so confirm the headlight type on your car before buying.
The high beam bulb is listed as 9005. This applies to the standard high beam setup shown on the page.
Yes. The sedan and wagon use different rear lighting bulbs. Sedan brake and tail light bulbs are listed as 3157R, while wagon brake and tail light bulbs are listed as 1157R.
The front turn signal bulb can vary by version. The page shows 1156A for one option and 1157A for another option, so it is important to verify the bulb already installed in your car.
Both the parking light and the front side marker light are listed as 1157A on this page.
The license plate light uses 168 or 917. Either bulb size may be shown depending on the exact lamp housing or replacement preference.
Both the dome light and map light are listed as DE3175. That makes it easier to replace the interior overhead bulbs together if needed.
The courtesy light is shown with two compare-to-original options: 194 or 7441, and DE3021. Because the page includes more than one option, checking the original bulb is the safest way to confirm fitment.
The trunk or cargo area light is listed as 2825 or 98. Wagon versions may also show a separate cargo light listing of 912 for certain positions.
For the sedan, the center high mount stop light bulb is listed as 921. For the wagon, the center high mount stop light bulb is listed as 912.
The rear turn signal bulb for the wagon is listed as 7440. This is different from the sedan rear turn signal bulb, which is 3157.
The sedan back up light bulb is listed as 3156, while the wagon back up light bulb is listed as 1156. Be sure to match the bulb to the correct body style.
The front fog light bulb is listed as H3C or H3. If your car has factory fog lights, check the existing bulb marking before ordering replacements.
Because the 2001 Subaru Legacy can have trim and lighting differences, the installed bulb is the best reference for fitment. This is especially important for shared positions like front turn signals, courtesy lights, and headlight setups where more than one bulb option appears.
