Quit Flashing Your Headlights at Red Stop Lights, Here Is Why
If you are one of those people that flash your headlights to get a red light to turn green, stop because it isn't working. Most stop lights are set for timers or they have infrared sensors that flashing your lights will not work on. They also have sensor rings that sense the magnetism of your car and flashing your lights will not help those kind either.
There are a few lights that have a regular camera and they can sense light changes like flashing, but they are not on many main intersections. I know the 4th and Edison light has one of those camera lights because I make it switch ever Friday when I come home from the club.
