Rear Light connection problem.

[Pawel1976]

Hi. Maybe someone knows how to connect the rear light.

Controller - blue, red, JST plug
The rear light - blue, red, yellow, green.
As on the picture.
I had this light on my old bike with brakes wire etc. Now, on this new controller Ive got only simple two wires.
Thanks in advance

Seems like your light has additional functions that aren’t supported by your new controller, you can check with a multimeter on the diode setting to see which wires are positive and negative. I’d assume you connect red to red and blue to blue, and just ignore the other wires, but you should verify it to be safe.

It was blue and yellow to the controller and I left with green and red. I know this light has normal position light plus brake signals. Does two wires I left with are brake signals? If yes, how can i connect it?
For example, green/red wire to the controller light wire and controller brake wire?
