Just installed the wunderkind short rear fender with multi function lights.
Love the Wunderkind product but also would love to try the Kellerman Atto 3-in-1. Spotted them at last years Motorcycle Live and gave them a little test - I happened to be looking directly at the lights when test was still seeing spots hours later, they are bright!!
Got the US-spec multifunction currently and like the blinking red light aesthetic but may fall fowl of the plod/MOT inspector at some point.
Mainly asking questions out of stupidity since 2017
