it would suck if you wired it so the vehicle blinks left and the trailer blinks right LMAO
I was driving behind a vehicle with a trailer that did that. It was really confusing when the right turn signal came on but there was nowhere to turn right. When they turned left I couldn't help but laugh.
It's definitely a good idea to check to make sure they're right before you start driving.
