Try racingplanetusa dot com. I have an Agility 125, but they provide parts sourced from Germany, just takes a little time to arrive. You drill down thru make, model (or a close equivalent euro-spec,) then “spare parts,” and I see similar complete assemblies with wires for about $100 each. I’ll bet they are LED fittings. Just beware that that might require you buying a separate flasher unit later-on, as well. For my Agility, the lower wattage bulbs created hummingbird-speed flashers till the appropriate flasher unit arrived! No Guarantee that the parts are 100% compatible, for my application, all connectors were similar. But the main harness, which I didn’t need, had several differences from US spec. Good Luck. Hope they work out. And I hope I successfully found the right scooter for you on their page!
Edit: I am assuming these would _replace_ your other US signals. If in addition to, there might be other issues, I don’t know.
