I need advice...
The off side rear light needs a new bulb.
The lower screw fixing the red "glass" is easy to remove.
The upper one just turns and turns...and does not release.
I suspect the captive nut isn't any longer captive and the screw is corroded into the nut.

So, how on earth do I get the screw undone without breaking the glass?
I've squirted 3 in 1 penetrating oil..we shall see what happens in the morning.
If that fails it seems my only option may be to drill out the head of the screw. As the screw rotates that could be difficult...

Has anyone else been in this pickle before?

Responses awaited...
