Just riding along on a little bumpy chipseal road when hear something hit the ground. Not sure if I ran over something or something fell of the bike. Circled back and my light was on the ground in a few pieces. Could not find one of the batteries, but the rest seemed fine.
The light did not come of the bracket, rather the bracket broke in half. It was one of those 90 degree metal brackets that come with rear racks and attach to the rack with a screw.
I am guessing that over the year making small corrections to the direction of the light caused the bracket to bend at the same spot and eventually weaken and then break with a minor stress.
So my warning is to avoid bending the metal attachment bracket if you can. Will probably buy a rack that has the mounting bracket built in, as needed a new rack anyways.
