Now and then when I see cars forgetting to turn on their headlights or if I need to warn them of hazards ahead, I find flipping the headlights on and off or flashing my highbeams with lights off much more effective than otherwise.
Besides, with DRL, I hate to get into situations where others would flash at me thinking that I have accidentally left my lights on.
While I'm not sure how much wear and tear DRL would cause, I rather have the option myself when to turn on and off the lights regardless.
Perhaps I'll need to fix up this DRL problem in the US?
Thanks for all the input.
