On my Alfa, and most Italian cars, all lights go off when the ignition is turned off and I am accustomed to always leave the lights on. I have been caught out with the Morgan on one occasion because the side lights were on all day.
I would like to work out a relay system that turned off all lights when the lights are switched to headlights but allowed the side lights to stay on if the switch was set to side lights only. I suspect this may require that the switch itself is modified.
Any ideas anyone?
