2015–2019 Subaru Outback Headlight and Bulb Sizes

Which Subaru Outback model years does this cover?

These headlight bulbs specifications apply to every Subaru Outback built from 2015 through 2019 — the BS (5th generation), mid-size wagon/crossover. Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What changed during the 2015–2019 Subaru Outback

• 2015Full redesign: all-new FB25, 3.6R moves to CVT, EyeSight driver-assist available for the first time on Outback
• 2018Facelift: revised front/rear styling, updated Starlink infotainment, standard EyeSight on most trims
• 2019Final year of this generation; last model year covered by the FB-engine oil-consumption settlement window

What headlight bulb does a 2015–2019 Subaru Outback use?

H11 (halogen; steering-responsive LED available on Touring from 2018) for the low beam and 9005 (HB3) for the high beam. Trims with factory LED or HID projectors use a sealed assembly instead and are not bulb-serviceable.

Can you put LED bulbs in a 2015–2019 Subaru Outback?

Physically, yes, LED replacements exist in every common base. Whether they work well depends on the housing: a reflector housing designed around a halogen filament scatters LED output into oncoming traffic instead of down the road. Projector housings tolerate the swap far better. Some vehicles also flag the lower current draw as a bulb-out fault.
