what is day time running lights and automatic headlights?

auto is when they come on at a certain point of darkness. Daytime means they are always on except for when you actually turn headlights on.  You can turn your days off by gently pulling up just a bit on your parking brake.

Are they supposed to come on automatically at dusk? Check your manual. If they are supposed to come one automatically, and none of them do, then there must be a short in the wire from the automatic switch or the switch or electric eye component must be dead.

You need to adjust your headlights, they are likely pointing too high and you are setting off the light sensors on the light poles that turn the lights on and off.

I would guess that we use a car,because we all know what they are. We also know that cars have headlamps located on the front. We further know that the light is projected so as to illuminate the area in front of the car. What we DON'T know, is how to get one of them to move at C...No, not even your best chevvy.

Most race cars do not have headlights, but depending on the class and type of racing some do.

I know the new Mercury and Lincoln vehicles with the LED's don't seem to flicker much, but I agree it seems that Cadillac's have a bit of flicker to them. Maybe they should put one of those epilepsy warning stickers on the back of 'em!

The car, you, and the headlights would no longer exist.  Light would continue at its usual speed.

There is a very common myth that it has something to do with farmers, but it is actually and energy conservation measure.  The whole idea was originally a big joke made by Benjamin Franklin.  Not all States in the Union do DST, nor do all Counties in every State.\n\nInterestingly enough, in these days of ubiquitous air conditioning, there may be no cost savings in lighting as was originally intended.\n\nThe reality is that the "Spring Forward" portion of DST causes additional traffic fatalities.  It is a dangerous practice that is continued thanks to governmental inertia and constituent apathy.
