Both Blinkers blink when i turn on a turn signal

I believe LEDs must have a resistor wired in series to operate in a 12V system, because full system voltage (~14V) will simply fry them otherwise. The commercial ones typically have the LEDs & resistors mounted together on a little circuit board. The 'prewired' singles have a little one soldered directly to the led leads & usually covered w/ shrink-tubing. The way those are nestled into the peg bracket, I'm gonna guess that they're not the 'prewired' variety, but instead have a single one somewhere in the wire running to the bracket.

I do think the best way to fix it would be to add a little resistor in series (in-line on each + wire), not those big resistors in parallel (branching from the + wire to ground). They're like sticking little heaters in your wiring harness - gotta worry about what they're near, and it's just an 'ugly' solution, IMO.

I know all this babbling is making it sound more complicated than it really is - hell, if you were closer to Nashville I'd say just bring it on over & I'd help you square it away.

Edit: Oh - and a BIG plus-one on adding an inline fuse to the power outlet. Attach one lead to the batt, and the outlet to the other, so the circuit is protected closest to the source.
