Both Blinkers blink when i turn on a turn signal

I must respectfully disagree. If it were in series, it wouldn't need to be nearly the size (power/wattage capacity), since it would only be passing a few milliamps. 'Load' resistors are way lower resistance (3~6 ohm) than a series resistor would need to be, and intended to wire 'across' (in parallel with) the LED to basically simulate the high current-draw of a normal bulb.

This one is 3-ohm, 50 watt:

Here's a cool little calculator I found: http://www.hebeiltd.com.cn/?p=zz.led...lator#parallel

Plug in 14V, 2V drop across led (lower than I thought), and 20ma for a single LED = 600-ohm, 1/2-watt (with safety-factor) required. For 6 similar LED's in parallel: 100-ohm, 3-watt

Shit - I really need to get back to this mess I'm procrastinating on fixing @ the day-job!
