ps: just so it is said, i want them to flash for a bit then go solid, not continuously flash.

Let me get this straight. You want your turn signals to hyper flash for just a bit, then go solid as if you turned the turn signal off? 1) that sounds counter productive, 2) that is unsafe, 3) hyper flashing is what your car does when it thinks a bulb is burned out.

The reason LEDs usually hyper flash is they do not draw enough power to make the car think a bulb is there, hence the car thinks it is burned out and it hyper flashes. There is nothing you can "add" per-say to the wiring to make it do this. There is, however, things you can add to the wiring to prevent it from hyper flashing.
