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 2018 Subaru WRX bulb size page helps you verify the correct replacement bulb by lighting position, so you can match the right part to the right lamp before you buy. Because the WRX can use different headlight and fog light setups depending on trim, package, and market, checking the exact location is the safest way to confirm fitment.

Use this guide to identify the bulb type for the headlights, fog lights, turn signals, reverse lights, parking lights, license plate lights, interior lamps, and more. Whether your 2018 Subaru WRX has halogen headlights or factory LED lighting, the bulb chart below is organized to make replacement faster and less confusing.

Fitment can vary on the 2018 WRX depending on trim level, lighting package, and whether the car has halogen or LED headlights. For example, the low beam and fog light bulbs are different on halogen-equipped cars than on LED-equipped cars, and some models with the eyesight package use a different fog light setup. If you are converting to aftermarket LEDs, make sure the bulb base, depth, and connector style match the original housing, since a bulb that fits physically may still not work correctly in the reflector or projector. When possible, compare the old bulb before ordering, and check the bulb already installed in your car if you are unsure about the exact specification.
