PIAA 15211 H11 Xtreme White Plus

PIAA 15211 H11 Xtreme White Plus

Xtreme White Hybrid bulbs are worth it if you want the lightest possible. They're brighter and provide better contrast versus stock, allowing drivers to see farther with greater safety on dark roads or high traffic areas like city streets at night time - because these lights don't have any filters that would interfere with their visibility! Made from quality materials such as quartz glass alongside our special alloy filaments which reflect heat much more efficiently than common metals do; this means they will last longer without getting too hot and eventually cracking under pressure (which can lead us to an accident).

This 2017 Subaru Legacy bulb size guide helps you verify the correct replacement bulb by lighting position, so you can match the right fit before you buy. Whether you are replacing a headlight, brake light, license plate lamp, or interior bulb, the layout below is organized to make bulb lookup faster and easier.

The 2017 Legacy uses different bulb types depending on the lamp location and the vehicle’s lighting package. Some positions use LED assemblies, while others use replaceable halogen bulbs such as 9005, H11, 921, 7440A, or D4S, so checking the exact position is the best way to avoid ordering the wrong part.

Fitment can vary by trim, market, body style, and lighting package, especially on models with halogen headlights, HID headlights, or the eyesight package with steering responsive fog lights. If you are considering an aftermarket LED conversion, make sure the bulb base, depth, polarity, and beam pattern are compatible with the housing. For the most reliable result, compare the bulb listed here with the bulb already installed in your Legacy before purchasing, since previous repairs or factory options can change what is actually in the car.
