I'm curious if you have similar issues if you just take one of the incandescent bulbs out and do not have any LED bulbs in your circuit. This may help you eliminate issues that do not depend on the LED question. LED's have low current and 12 volts can be measured at the hot side of the bulb when on. This is similar to open circuit condition.

I think it is some sort of cross-talk issue through the flasher, turn signal or trailer relay unit. That it's picking up the license plate lamp and flashing it is also wierd. About the only thing these 3 cirucuits have in common is the battery and grounding through the frame to the drivetrain.
So, you are suggesting to remove one of the four 1157 bulbs and try the turn signals and brakes to see what I have on the remaining 3 bulbs? Or jumper the power and ground at the removed bulb socket?
