Turns out I can run an LED bulb with the single-coil my engine already has. Would need dual coil to run the non-LED stock bulb this bike came with, because LED needs less energy I guess.
In the youtube video above GPS linked the motorcycle bulb they found can be swapped with the stock bulb.
I basically just need to make a pigtail.
This is the LED bulb they say to use: WinPower S2 Ba20d
It has a High and Low but hopefully it's always on High because I'd like it nice and bright but if anyone happens to know the strongest bulb I can run with this configuration please go ahead and link it, even if it's a 'maybe' and I can return it with free return shipping I'll give it a try. But I think this should be bright enough.
Worth noting for different type of potential bulb recommendations (CREE / COB) that in the tutorial video he says to bypass and remove the Regulator to use the LED, but mine is missing that Regulator but I can get it sent to me free from GPS since my order was severely damaged by UPS handling and they've sent me a bunch of missing parts no problem since then.
