Just thinking about Ronnies idea of a diode in the system.
If I was to put a diode in the L/H wire from the double pole switch
So the power can't return from the indicator to the Idiot light.
But can go in the other direction from the Haz switch to the L/H lights.
Now we're talking..........."lektronikery"...
Would it work, if so then what do I need?
