I just receive my 3 LEDs from superbrightleds.com and installed them for the oil, neutral, and turn signal indicators, and they all work fine with no complications. I have no other LEDs on the bike. Like it was said, I think the trick is to use those special WLED 6-LED bulbs because, like Reido said:"These LED's are Non-Polorized, so they are supposed to work in any direction." I guess I won't have to install any diodes unless I install LEDs for turn signals, but someone said the LED turn signals (24 LED bulbs) were not any brighter that the original filament bulbs, so I guess I am in no hurry for that swap.
