I think the easiest solution would be to standardize a headlight switch. In my car, the switch has four options - Automatic, OFF, Parking Lights, ON. I leave the switch in Automatic, but I've had the car returned from service with the switch in the OFF position before. Even in OFF, the DRLs and the dash lights still operate normally. I like being able to turn the lights off sometimes, but I'd prefer if the switch went OFF, Automatic, Parking, ON, with OFF being a momentary override. I think all cars now control the lights through a body computer, instead of a traditional relay, so the OFF override could be programmed to keep the lights off for a set period of time, or perhaps until the vehicle is restarted, at which point automatic mode takes over again. My truck only has Automatic, Parking, ON, and sometimes I'd like to be able to keep the truck running with the lights off (for example, warming up in a dark campsite and trying to preserve my night vision).
