Every bulb on this vehicle
Headlights get the attention, but the small bulbs are what fail an inspection. A burnt-out brake or turn bulb is also the cheapest ticket you will ever get, and most of these are a few dollars and a twist to change.

Why this keeps getting harder
Headlight bulbs used to be a commodity: a handful of codes covered most cars and any of them cost a few dollars. That is ending. Across the vehicles we hold specs for, factory LED low beams went from 0% of 2000s cars to 59% of 2025-and-newer ones. LEDs last far longer, which is the upside and a real one. The tradeoff is that when they do fail, it is often not a bulb you can buy at all, and the fix moves from a $20 part to a headlight assembly.

Equipped trims use factory LED headlights, which are sealed assemblies rather than replaceable bulbs.
Is the 2025 Subaru Outback headlight bulb a DIY job?
The 2025 Subaru Outback has factory LED low beams. Factory LED headlights are often sealed into the assembly rather than being a serviceable bulb, so before you buy anything, check whether yours actually comes out.
