@ Lincsman, the ones on the racks are wired to the feed for the auxiliary front lights but you could go from the back light feed. I have now moved them to a bracket fixed to the topbox rack as on the pannier racks they kept blowing from the vibrations. The ones on the topbox are brake lights about the right height for car drivers not to miss, Its a bit of a tight squeeze to get to the wires and that's why I did the back lights to the other auxiliary lights. all of them are the cheap ones of flebay.
