Why do cars nowadays have such ridiculously bright headlights?
In: Engineering
Most cars with LEDs utilise a system that supposedly dynamically changes the light beam by controlling each individual LED to manipulate its shape and direction. This system works mainly through the front facing camera constantly monitoring the conditions in front and the car’s computer tries to use this data to adjust the lights accordingly. For example if the camera sees oncoming cars, the onboard computer tries to create a gap in your light beam so that you don’t blind the oncoming driver but you maintain good forward visibility even if you have your high beams on.
At least that’s the theory. In practice it doesn’t work that well, so oncoming and following cars often blind us and it can often appear as if the lights are flickering or flashing. That’s the lights trying and failing to adjust themselves properly.
