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 Outback bulb size guide helps you verify the correct bulbs by lighting position, so you can replace the right part the first time. Because Subaru used different lighting setups depending on trim, package, and market, it is important to match the bulb to the exact location on the vehicle.

Use this page as a quick reference for common exterior and interior lights on the 2018 Outback, including headlights, brake lights, turn signals, reverse lights, license plate lights, dome lights, map lights, and cargo area lighting. Checking by position makes it easier to compare halogen and LED options and avoid buying the wrong fitment.

Fitment can vary between trims and lighting packages, so always confirm what is installed on your Outback before ordering replacements. Some positions may use halogen bulbs on one version and LED assemblies on another, and aftermarket LED conversions may require different bulb choices, resistors, or adapters to work correctly. If you are replacing a bulb that is still accessible, the safest approach is to remove it and compare the base, shape, and connector before purchase. That is especially useful for headlights and fog lights, where the listed options can differ by configuration.
