Attention
A Light / Lamp for our KT controller ,it must be about 70 mA ( less than 100 mA )or the controller will be damaged. I suggest you do not use the front and rear lights at the same time.

1.KT controller only compatible with KT display .Same communication protocol.We have given pictures to teach you how to distinguish.Please check before place the order .
2.Even its KT system. Waterproof cnnector is special that I can///'t promise it will 100% compatible and work. Because of line sequance . Our controller cable brand is Julet.Please check and confirm yours on the appearance of connector.Including cable brand as I know kind of Julet Higo YLS .Usually 90% of them will work well. Please contact with us if you have problem when install it.We will try to help you to solve .
3.Compare with sinewave and squarewave .Sinewave means less noise.more smooth when riding.
4.Please contact me if you are not sure which is right for you or have further questions by Aliexpress message.
5.The cable length is manually measured, there may be some difference, please understand.
