led tail lights blinking

....indicating a short in the wiring like I mentioned if you still have a conventional flasher.

4x4Dually is right on this. When you hook up a trailer the blinker would start to blink really fast. Reason being is your hooking up a resistive load in parallel which increases the amperage on the circuit(also through the flasher) more current makes more heat, which causes the bimetal(similar to what is used in the older thermostats) to heat faster. When it heats, the metals(bi means two)expand at a different rate causing the contact to warp.

I guess I'm an idiot but my LEDs I had before blinked normal and these blink fast

Have you put put the first ones back in to see if they work the same "post smashed by a tractor"? Just a quick sanity check for the wiring. No one said you were an idiot....we are just saying it probably isn't the flasher. We are just trying to help feller.

No I threw those away but i did check it with a stock set and those worked fine

jake it sounds to me like you need to pop your hood and check your blinker fluid bud...
