I've just replaced my front turn signals from 21watt bulb fittings to LED clusters, unfortunalty these don't draw enough power from the circuit to trigger the flash correctly, i'm getting a very slow flash rate and no turn indication in the vehicle. When I reattach the bulbs it works fine so I know I havent fryed anything. I need to find a good resistor setup to simulate the load the original bulbs would have had on the circuit, then wire the LEDs in paralel.

Could anyone with more understanding of Ohms law and didn't flunk math help me please.

John.
