-Your flasher is nothing more than a bimetallic strip between two contacts. Current flows through this strip on its way to the turn signal, and when too much current passes through, the strip warps up and breaks the contact momentarily because the inside of the strip expands more quickly with heat. It cools and returns. If you are blinking too fast, too much current is flowing through. You don't need to buy anything more than a few resistors from radioshack and wire them in series with each blinker. Just measure the resistance of your old light, and your new one, find the difference, and go buy that resistor. Should get you back to normal. And shouldn't cost more than a buck or two at most.
