TEQIN Ebike Headlight and Tail Light Sets, 24V - 48V Front Rear Warning Lights Kit, LED Night Spotlight Cycling Modification Parts, E-Bike Headlight Turn Signal Rear Light with Switch 24-48V

So I got this kit because I like the switch and harness and tail light…..if you want your break lights to work connect loop white from on the harness to your e-bike brakes for 2 pins brakes loop the red and black…. For 3 pins what worked for me was white and black and left the red alone.All its doing it completing the ground circuitOther then that the light and horn is whatever.I made a custom sm 3 pin to use my own light and horn but off the switch, green is light switch, black is ground red is horn switch.I basically just bought the kit for the switch, harness, and brake light with turning signals. Super helpful picture helps if I typed it confusing, sorry of its hard to see text might be small I just made it quick screen shot to zoom inAt first I plugged the power to a 12v and everything worked but the brake light wouldn’t turn on but signals worked but very faint then plugged it straight to a 52v e-bike battery everything finally worked with bright light and very loud horn… I plugged it into the 72v e-bike battery and everything worked again even brighter…. Horn only had a couple uses before it blew out tho lol but the switch and rear tail light works just fine..Just gonna got with a 24v step down from my 72v to power everything safely
