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 page helps you verify the correct bulb sizes for the 2003 Subaru Impreza by lighting position, so you can match the right bulb to the right socket before you buy. Because Subaru used different setups depending on trim, body style, and market, it is smart to confirm each exterior and interior lamp separately rather than assuming one size fits every location.

Use the chart to check common replacement points such as headlights, turn signals, brake lights, parking lights, license plate lights, dome lights, and cargo-area bulbs. The 2003 Impreza can use different bulb types for sedan and wagon applications, so this guide is especially useful when you are replacing multiple bulbs at once or comparing a failed bulb to the original part.

For best fitment, compare your installed bulb to the listing before ordering, especially if your Impreza has an optional lighting package or a nonstandard trim. Halogen bulbs and LED replacements are not always direct swaps: LEDs may need polarity checks, may change brightness or beam pattern, and can trigger fitment issues in some housings. If you are converting from stock halogen to aftermarket LED or HID-style setups, make sure the bulb base, connector, and housing clearance all match. When in doubt, remove the old bulb and verify the number printed on the base before purchase.
