I've tried looking for guides, but I haven't seen any other lights like mine
It seems like there is a cover over the bulb but I haven't been able to remove it and even if I could I don't think the bulb could fit out.
I've tried twisting the white case but there is no movement.
I can't see any clips
There are some screws, but I haven't seen any other fittings that need anything unscrewed to get to the bulb.
The second picture shows how far I am able to pull the fitting out
