If you just type in 2x For BMW F800GS R1200GS Motorcycle LED Auxiliary Fog Spot Light Driving Lamp on the auction site there are lots that come up, I have used them with the switch kit and also with another switch and my own wiring set up.
I used them on the NC 750x's that I commuted on in all weathers and they where a godsend in the winter on unlit roads.
