small modification on vin 4616,
I was tired of this ultra capricious headlight switch, even after changing to a new model, the problem was always the same, as soon as there is heating or even having modified the relay or lubricated, nothing nor done in the long term.
Nothing more annoying than not being able to put the fires on or turn them off.
I therefore removed the mechanical blocking of the switch and I made a small electronic module based on Arduino which is the same birch as the 2 original positions of the switch.
and finally no more problems
