Nothing groundbreaking here, either, but I found a clean fix for mounting my magicshine tailight to my rear rack. Like the dinotte light, it too is designed to be mounted to a round surface such as seatpost. My trunk bag, however, hides the seatpost and my rear rack had the standard flat little mouning surface designed for clip on or screw on tailights. I first tried a piece of pvc pipe kept in place with some picture hanging wire and hole drilled into it. It was functual but it tended to bounce. Screws probably would've worked better but I still didn't like the appearance. I then tried one of the small half cylinder building blocks (from my son). I covered it and secured it using black "sticky ass tape". Very clean and much more functual.
