This bracket mounts an LED tail light under the rear rack of the Funhang EB-C2 e-bike. It is secured using four zip-ties. It's designed for this common e-bike tail light: https://www.amazon.com/dp/B08HYCMMZB

I ran the wire for it down one of the rack supports on the right side, then into the frame along with the motor wires. I used a y-cable off of the headlight wire, and soldered on the correct plug to the tail-light wire, and then plugged it in up at the front of the bike.
