Toggle switches

[M.Morren]

Thank you Jordan,

I actually used your diagram and it did help me understand the working too!
Now I just have to figure out how the gentlemen that told me that all three should be turned on to get the headlights to turn on (as a sort of failsafe to not accidentally turn on the bright headlights) got that info from. He dismantled several Chevs so he must have seen some different configurations. It is possible to wire the switches in the above mentioned way due to the independent output sockets.
I'll visit him in a couple days to see how his Chevs are wired and will share this with him to see what he thinks.
Thank you both for the help and if anyone else has some extra comments, feel free to message me or put it in this thread!

Cheers!
