If you haven’t already looked into the headlight light switch, you may want to look there it is known to wear out.
I would also recommend doing a search for faulty ignition switch problems as they are also known to go bad and when they do they will produce strange electrical gremlins.
I haven’t heard of any faulty current distributors on the forums other than one & it seems that was possibly a result of reversed polarity of the battery.
You should also be aware that there is only one rear fog light.

If you’ve already looked into these then hopefully someone else will be able to steer you in right direction.
