Eli5, Why do turn signals flicker quicker when they are broken?
gpt
They're designed to do that to warn you (and maybe others on the road?) that there's something wrong with your turn signals and you should get it checked. Usually it's a busted/burned out bulb. Park your car, turn on the signal on the side that's flickering quickly, and check the bulbs to find out which one is out.
