PIAA 19617 9007 (HB5) Xtreme White Plus

The Xtreme White Hybrid bulbs are brighter and more visible than stock, allowing you to see farther for greater safety. Made from high-quality quartz glass with an alloy filament design that is far better at dissipating heat so your lights don't burn out too soon! Xtra White has all of these benefits but also delivers rich colors as well thanks in part because it uses both white LED's alongside some yellow ones which give off a warmer glow when combined together unlike other fixtures where only one color would be present.

This 2003 Subaru Legacy bulb size page is designed to help you quickly verify the correct replacement bulb by lighting position. Whether you are changing a headlight, tail light, interior lamp, or license plate light, the bulb chart below organizes the common fitments for this model so you can match the right size before you buy.

Because the 2003 Legacy was offered with different body styles and lighting packages, bulb sizes can vary by location and trim. Use the position-specific listings to confirm the exact bulb for your sedan or wagon and avoid mixing up similar-looking bulbs that are not interchangeable.

Trim and package differences can change the fitment, and halogen bulbs should be matched carefully if you are replacing them with LED alternatives or other aftermarket options. If a socket or lens has been changed before, the installed bulb is the safest reference, so remove the old bulb and check its number before ordering a replacement.
