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.

Frequently asked
What headlight bulb does a 2025 BMW X1 take?
Equipped trims use factory LED headlights, which are sealed assemblies rather than replaceable bulbs.
Can you replace the headlight bulb on a 2025 BMW X1?
Before you shop: the 2025 BMW X1 has factory LED low beams, and on this vehicle they are not a replaceable bulb. The LEDs are built into the headlight assembly, so there is no part number to buy and no bulb to swap. If a low beam has failed, the fix is a new headlight assembly, which is an order of magnitude more expensive than a bulb and worth getting a diagnosis on first - LED headlights usually fail at the driver or a connector rather than at the diodes themselves, and that is often repairable.
