Friday must have been a slow day at New River Auto Mall in South Carolina. That's good news for us, though, because it gave the guys who work there time to put this ridiculous video together.

Have you ever been in a turn lane and started to wonder why your turn signals don't match up with the other drivers' signals? Stuff like that drives me nuts. Well, the folks at this dealership ran a little experiment where they tried to get the hazard lights on their A4s and S4s to blink together at the same time.

I have no idea how long it took them to do it, but they pulled it off. And there's even a crazy light show set to some music at the end. 

Hey guys, does your boss know you did this? Or was he or she in on it too? Sounds like a fun place to work. 

Hat tip to Chad!
