PIAA 15224 H4 (9003 / HB2) Xtreme White Plus

Xtreme White Hybrid bulbs are great for down-road illumination, giving you the ability to see farther with greater safety and comfort. Made from high-quality quartz glass as well as alloy filaments that won't break or bend under pressure like regular metals can sometimes do! The Xtra white bulb's construction allows it to withstand intense heat longer so they last much longer before needing replacement which costs less than when replacing them every few months because of their quality material use in combination with far better-distributed weight throughout each unit making this an investment worth having even if just once.

This page covers bulb sizes for the 2001 Subaru Forester and is organized by lighting position so you can verify the correct bulb before you buy. Whether you are replacing a headlight, brake light, dome light, or license plate lamp, checking the exact location helps avoid mix-ups and makes the repair faster.

The 2001 Forester uses several different bulb types depending on where the light is installed, and some positions may vary by market or body style. Use this guide to match the bulb to the front, rear, interior, or cargo-area lamp on your vehicle.

Fitment can vary with trim level, lighting package, and regional specifications, so it is smart to compare the bulb currently installed in your Forester before ordering. This is especially important if your vehicle has been converted to LED, uses an aftermarket housing, or has had previous repairs. Some replacement bulbs are direct halogen-style matches, while LED upgrades may need additional compatibility checks for beam pattern, brightness, or warning issues. When in doubt, remove the old bulb and confirm the base and number printed on it before purchase.
