I'm trying to figure out how to modify my tandem light switches so that the lights turn off when both switches are either up or down, and turn on when they're in opposite positions. It seems like this should be the standard setup, so I'm looking for some advice on how to achieve this. I think just flipping one of the switches might be the easiest solution, but I'm concerned about any potential electrical risks involved. Any tips would be great!

Yep, that’s exactly how three-way switches typically work. Someone probably flipped one of them incorrectly. Just take off the cover and carefully flip one switch back. If you’re uncertain about it, shutting off the breaker is definitely the safe way to go!
You don’t need to mess with the wiring at all! Just remove the cover of one switch, unscrew it, and rotate it 180 degrees before putting it back in. That should do the trick! Just a heads up, it’s a good idea to turn the power off before you start messing with it.
Honestly, if you’re asking this kind of question, shutting off the breaker first is a smart move! You might not always have to do it, but it’s better to be safe than sorry, especially if you're new to all this.
