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.
Sure. Maybe I was a bit dramatic when I typed the reply. I know how annoying some other drivers are and how they make it worse for everyone. I wouldn’t even be mad at you if lost your cool. And I’m not against using indicators or flashing your lights at people. That’s kind of why we have them in the first place. Only thing I’d have a problem with is brake-checking people or intentinally getting too close. Flashing or honking to signal them to get out of the way is pretty alright in my eyes.
