This 2003 Subaru Outback bulb size guide helps you verify the correct replacement bulb by lighting position, so you can match the right part before you buy. Because Subaru used different bulb types for different lamps, it is important to check the exact location on the vehicle, especially if you are replacing headlights, tail lamps, or interior lights.
Use this page as a quick reference for the 2003 Subaru Outback, whether you have a sedan or wagon body style. The bulb chart below covers common exterior and interior positions and can help you confirm the proper fit for high beam, low beam, parking light, license plate light, dome light, map light, brake light, turn signal, and cargo-area bulbs.
Fitment can vary by trim, lighting package, market, and body style, so always compare the bulb position on your car with the chart before ordering. Halogen bulbs are the standard fitment for this model, but some owners upgrade to LED replacements or use aftermarket conversion kits; if you do, make sure the bulb base, polarity, and beam pattern are compatible with the housing. For the best results, check the bulb you remove from the vehicle before purchase, since the installed bulb is the most reliable confirmation when a trim difference or previous repair may have changed the original part.
The 2003 Subaru Outback uses H1 bulbs for the low beam headlights and 9005 bulbs for the high beam headlights.
The center high mount stop light uses a 921 bulb on this model, though wagon and sedan applications can differ in some lighting positions.
The license plate light bulb can use 168 or 917, depending on the exact lamp setup listed for the vehicle.
Both the dome light and map lights use DE3175 bulbs on the 2003 Subaru Outback.
The parking light bulb and the front side marker light bulb are both listed as 1157A.
The front turn signal bulb is listed as 1156A for one fitment and 1157A for another, so it is important to match the exact lamp configuration on your Outback.
Rear turn signal bulb fitment depends on body style: the sedan uses 3157, while the wagon uses 7440.
For the sedan, both the brake light and tail light use 3157R. For the wagon, both the brake light and tail light use 1157R.
The sedan back up light uses 3156, while the wagon back up light uses 1156.
The sedan trunk or cargo area light uses 2825 or 98, while the wagon cargo area light uses 912.
No. The sedan center high mount stop light uses 921, while the wagon center high mount stop light uses 912.
Yes, many positions can be upgraded to LED, but you should confirm bulb size, fitment depth, and compatibility with the housing. Some LED bulbs may not match the original beam pattern or may need polarity correction.
Checking the installed bulb is the safest way to confirm fitment because previous repairs, trim differences, or market-specific equipment can change what is actually in the vehicle.
