So I think this would work for glowing blinkers. It depends on having the individual current control at the blinker as the ones I've installed already have - which means I just might test this out if I get bored at work again. Haha. There's a diode to keep this circuit from filtering back into the rest of the bike, and two more to keep the blinkers from cross-feeding into each other. Theoretically, this should allow all four blinkers to glow at the same brightness as the taillight whenever the headlight circuit is on. When you activate a turn signal, that side then receives full power through the normal system, and blinks normally. I believe that the opposite side will remain glowing. If used with the LED blinker setup I've used here, I think you'd want more heatsinking on the LED's, because the little corner bracket might not cut it for continuous operation, even at reduced power. I'm perfectly happy with the amount of heatsink given that as blinkers, they seem to only be on at about a 30% duty cycle, and that only when I'm turning a corner or changing lanes. If this works with LED's, it should also work with normal bulbs, though the resistor would have to be adjusted to allow more current, as the 50mA current this is set at would not do a whole lot for regular bulbs, I don't think, and you'd probably want to heatsink the MOSFET as a precaution. Keep in mind each set of bulbs will get whatever current it's set at since they're configured in parallel.
