sadly no they are not wired to the blinkers (i wish). tried really hard to figure out a way of doing that with out cutting any factory wires, but i couldnt. i have them hooked up to the fuse for the parking lights so they are solidly on when those are on. there are also white lights that light up on them too and i hooked them up to the reverse lights.
do you have the lights on the side of your truck wired up to the blinkers so when you're turing the sides blink too or just the back ones?
