Hey,

I put some really cool LED turn signals on my Triumph 675, and they blink way too fast. I remember (a long time ago) using some sort of resistor to slow down the blinking. But I don't remember what kind of resistor, or whether it was wired in series or parallel.

Can someone shed some "light" on this subject?

you need to use a resistor.

I'm having trouble with putting LED signals on my Hypermotard, same issue. I purchased Targa resistors intended for this, but they did not work. I think it's because I replace LED signals (stock) with aftermarket LEDs, and they're a different resistance than conventional bulbs. So back to the drawing board.
