Somebody has to ask this question:-)

Multi function filament bulb set. Chinese manufacture (in case you
wondered) fuse OK but no lights. Appear to be well made.

Control box is sealed and has a single pushbutton to select the operation.
Is there any point in forcing the box open in the hope of by-passing the
electronics?

Check the fuse in your plug or try a different socket
