Why YSK: Your signals alert other drivers as to what you’re doing; a signal bulb costs a few bucks and is usually a quick and easy repair to do yourself (consult YouTube); and any place that regulates motor vehicles probably requires you to have working turn signals. So knowing when and how to replace a burned out signal bulb can save you an interaction with law enforcement.
Adding: You can diagnose which bulb is out by turning on your hazard lights and checking all four corners of your car. It’ll be the one not flashing.
This is also probably a good time to check your brake lights. Put something heavy on the pedal or have a friend hold it down and check that all three brake lights illuminate. Replacing a burned out brake light is also usually pretty cheap, quick, and easy.
Oh boy, do I have a surprise for you. Their cars blink the brake lights. You read that right. Bonus video
Interesting. I never thought the turn signals are amber by mandate in other places.
I can’t speak for everywhere, but in Brazil the emitted light must be amber by law. Some after market parts and some auto makers get creative and manage to put a red mask on it that somehow still lets amber light through. But it’s rare.
It’s not by mandate. It’s a bad fad that is unregulated. Front blinkers are still amber.
Edit: I misread your comment.
