What's going on with this headlight? (Pics)

My headlight seems to have a bulb out but I don't know what bulb this is.

I tried looking up the part number, but it looks like there are a few bulbs inside the headlight.

Does anyone know how to find the part number for this burnt out bulb? Or what it's called?

That's the xenon headlight bulb - https://www.fcpeuro.com/products/bmw...fD_BwE#fitment

The size is a D1s if you haven't found it yet as well. If replacing that doesn't work, it may be your ballast.

Thanks! Just ordered a bulb.

Is the ballast the same as the module? Because the shop said both the module is bad too.

You have an AHL Module and a Ballast. The ballast runs the bulb and the AHL Module controls the horizontal and vertical motion of the lens. The AHL Module will not cause the bulb to go bad.
