I'm compiling the list of winter projects and will be doing some rewiring and was counting circuits for the replacement panel. A thought came to me: why are there typically three separate switches to turn on and off the running, steaming and anchor lights? Each is mutually exclusive when in use. My car doesn't have separate parking, low beam, high beam switches. Wouldn't a 4-position rotary switch do the trick? Off-Running-Steaming (with Running)-Anchor
There must be a reason, because I haven't found such a switch panel at the major chandleries.
