Hi bought a new Burchda RX80 bike. I love it. Still, I wish it has a taillight with brake light. I bought a genetic taillight from Amazon and able to connect to the headlight wire from the controller. However, the controller doesn't have brake light output. That would have to tab off from somewhere. I wonder if anyone have done that. If anyone want to know how I install the taillight, post a request here then I will give you the details.
