Present your best argument for having an on/off switch for the headlights on your car, I haven't heard any that satisfy me. My $0.02: Lately I've seen a lot of people driving around in the dark (well past dusk...) without their lights on. If I was 5 seconds behind a particular left turn going home last night I would have been t-boned at 40mph by one of these (insert expletive here) folks. I can only assume that person was blissfully unaware their headlights were off, driving with their dash illuminated, oblivious to the fact that no one could see them. The fact that manufacturers put an on/off switch on the most important nighttime driving safety feature is completely ludicrous to me. The half-way "parking lights" setting that only lights your dash is even worse. Streetlights illuminate the road for you, and your headlights illuminate you for everyone else. Does anyone have a legitimate explanation for this? If it was my call, the ignition in the ON position would turn your low-beams on no matter what (also preventing you from accidentally leaving them on when you exit the car). Engine is running -> your lights are always on. You have an accessory setting for a reason: every other situation when the engine is off (go ahead and put your switch in this circuit.) I know most new cars have some type of running light (however dim), but it seems many still don't. Another vent to a bunch of folks I don't know, I'm excited for all the sarcasm and serious responses we might see here! At risk of sounding full of conviction, I doubt anyone can beat my argument. Happy almost weekend!
