It'll be faster and convenient to switch on, when it's soldered to my battery like the others, routed through one of the other or additional switches.

WOW !! amazing setup . . but I wouldn't want to go anywhere near a 48 volt battery and start soldering, which is why I took the easy route and just used a Y-shaped plug-in connector into the front-light wiring loom. Good luck with all of those lights and indicators if you do connect in Maybe even a "flashing blue light" for those emergency rides haha

If you did solder lights on, perhaps your battery would send messages reporting abnormal function via CAN bus?

 

I saw a video recently on Youtube, of a guy powering a CAN bussed Bafang motor with generic two wire battery.

If that wasn't illegal, I would have done it already - I have heat resistant blue acetate sheet. Haven't been stopped by the cops yet, ridden past them many times. These lights stop cars pulling out on front: three bright flashing headlights never fail to get me noticed by drivers in daylight, but they're too nauseating for me to view at night, even though they're all angled down at the road.

I don't experience close passing anymore either, or close cutting in front overtakes:

 

 

A little late to the party with this thread, but thank you for sharing your ideas with the lighrs running off the motor.

 

I read a lot of negative comments, and the opinions suggesting I’d end up with an explosion the size if Chernobyl if I decided to replicate your idea.

 

Anyhows, I decided to take a positive approach coupled with a bit more research. I found in the Bafang tech specs that the light output is rated at 12v and 12w, and there is separate feeds from the motor for the front and rear lights.

 

I found the genuine Bafang cables on eBay for £20 that plugged straight in, I bought some lights off Amazon for £30 that are correctly rated and powerful. All wired in and working perfectly, basically did the same as you did in your video so thank you for the post, it was most helpful.
