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.

This is the most utterly incorrect thing I’ve read this week 😂 Bimetallic strips? That type of lamp hasn’t been in use since the 1970s! And even then wasn’t used for indicators, just for warning lamps for roadworks!
Even a car from the 1960s onwards will blink at double speed when the (perfectly ordinary) bulb pops. If the relay detects a broken circuit, that’s what it does
What’s the Lemmy version of r/confidentlyincorrect?
