cheap LED flashlight zip tied on, less than five bucks. I also have a little zefal headlight mounted on the visor of my helmet. This time of the year a have the flashlight on along with two lights mounted on the bike for the moring ride ,no traffic 4:30 AM, and all four for the 5
o PM commute. The litte Zefal I put on flash mode, set-up works good.
