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 page helps you find the right bulb sizes for the 2021 Subaru Outback by lighting position, so you can match the correct bulb before you buy. Because Subaru used different lighting setups depending on trim, market, and body style, it is smart to confirm the exact lamp location first and then compare it with the chart on this page.

For the 2021 Subaru Outback, many exterior lights use LED assemblies, while some positions may still use replaceable bulbs depending on equipment. The bulb listings here are organized to make it easier to verify headlight, tail, brake, turn signal, reverse, license plate, interior, and cargo light fitment without guessing.

Fitment can vary by trim package, lighting package, and whether your Outback has halogen or LED equipment from the factory. That matters especially for headlights and fog lights, since some versions use LED units while others use halogen bulb types, and aftermarket LED conversions may not match the original beam pattern or housing design. Before ordering, check the bulb currently installed in your vehicle, compare the socket and connector style, and confirm whether your model uses a replaceable bulb or a sealed LED module. This is the best way to avoid buying the wrong part and to make sure the replacement works as expected.

FAQ

What bulb size does the 2021 Subaru Outback use for the low beam headlight?

The chart lists LED for some low beam headlight setups, and also H11 for low beam on other versions. Your exact fit depends on trim and lighting package, so verify what is installed on your vehicle before purchase.

What bulb size does the 2021 Subaru Outback use for the high beam headlight?

The chart shows LED for some high beam headlight setups, and 9005 for other versions. Check your existing headlight assembly to confirm whether your Outback uses a replaceable bulb or an LED unit.

Are the daytime running lights on the 2021 Subaru Outback replaceable bulbs?

The page lists the daytime running light bulb as LED. On many Outback configurations, this means the light is part of an LED assembly rather than a simple plug-in bulb.

What is the rear turn signal bulb size for the 2021 Subaru Outback?

The rear turn signal light bulb is listed as 7440A. Make sure to match the rear position specifically, since front turn signal fitment is different.

What is the front turn signal bulb size for the 2021 Subaru Outback?

The front turn signal light bulb is listed as 7444NA. This is different from the rear turn signal bulb, so do not use the same part for both positions unless your vehicle’s lighting has been modified.

What bulb does the 2021 Subaru Outback use for the reverse light?

The back up reverse light bulb is listed as 921. If your Outback has a different rear lamp setup, confirm the socket and bulb shape before ordering.

The map light bulb is also listed as DE3175. That means the dome and map lights may use the same bulb family, depending on the interior layout.

What bulb size does the 2021 Subaru Outback use for the fog lights?

The front fog light bulb is listed as H11 LED or H16 LED, depending on the setup. Because fog light fitment can vary, check the housing and connector before buying replacements.

Does the 2021 Subaru Outback use LED bulbs for the brake and tail lights?

The chart lists the brake light bulb and tail light bulb as LED. In many cases, that means the light is an integrated LED unit rather than a standard replaceable bulb.

What should I check before buying bulbs for a 2021 Subaru Outback?

Check the exact lighting position, trim level, and whether your vehicle has halogen or LED equipment. Then compare the installed bulb or lamp assembly to the chart, since Subaru lighting can vary by market and body style.
