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.

Search online for Kymco Agility Scooter Repair Manual.

Download it.  Look thru it for body panel removal info.

You might find something like this:

(If it doesn't show up,) open up seat, remove under-seat box, Remove black panel in front of same (I start prying from the lower front on this.)  Remove rear rack.  Remove colored body panels, via screws/push-plugs under edges.  You should now have access to rear of turn signal lights.  (This info good for US spec/original Agility, the Agility City versions are something different!)

Hope it works for you, removing the plastics the first time made me nervous something would crack , for me it worked out OK.
Good Luck!

Edit:  To completely remove the colored body plastics, the seat lock cable should be undone from the latch, pull cable loose from fixing, pivot to release end of cable from latch.
