Headlight on-off switch?

[Dizerens5]

I did once accidentally leave parking lights on all night on my last car which was a Chrysler Neon, near new at the time. In the morning the battery was totally dead, not even a light. Barry you're a Brit you may remember years ago a vehicle parked on an unlit road at night had to have parking lights on. It was mostly ignored but not in Essex where police were very interested in it. People seemed to manage ok so I suppose cars had higher-capacity batteries then.

Yes I remember parking lights. My old Merc actually still has them not that they ever get used.   The clever bit is I can switch only the 2 nearside lights on or the 2 offside lights with no instrument lights so that's less than 1 amp drain. The battery would survive over night but It's still not something I'd want to try.
