If the DC voltage is at least 12 volts or slightly more, I don't see this not working. I've tested these LED's on straight DC from a 14 volt motorcycle battery without blowing the internal capacitors.I may be wrong but idk if leds wikk work with that wiring setup.
I may be wrong. You may have to make it dc setup with a battery.
I hope someone chimes in that knows for sure.
I've also ran a set of halogen driving lights and an led tail light from a zx6r on my beach cruiser bicycle, as a joke, run straight off a motorcycle battery with only a relay to keep the switch from shorting out the wires.
I don't have the tail lights hooked up yet since I'm waiting for some money to come in so that I can order a few things I need to get the motor running, if it will run. It's stuck in gear and I have no clutch cable. It's a real pain to even try getting out of gear without a cable and lever. Even so, I now need an intake adapter so I can have the carb on the right side of the motor instead of the left because of that starter motor mount sticking up from the left cover and case. Then I need a 428 chain and a 428 rear sprocket before I can start riding again.
