There's another plastic insert below the main beam cover:
Turn this 90 degrees counterclockwise and pull it out to get to the indicator bulb.
I still can't find it!
Here's the two caps I can see, and can't see/feel anything under either.
But here is another cap which looks like it houses the xenon bulb?
Again can't see/feel anything underneath. This is very tight aswell can't really get under it.
