Just as I've picked up a rear red blinking light for my bike (again, to keep drivers from running me over), I've also added a triple LED front headlight. It produces a steady light or blinks… and is also required by law in Chicago for riding at night.
As you can see, it also nicely highlights my bike bag bracket, notable for that big grey splotch of epoxy. I cracked the bracket over 20 years ago, back when I used the same bag on my 10-speed. Hmm, maybe I should paint that spot black or something! (And if you are wondering how the light works while the bike bag is mounted, yeah, I'm working on that solution as well!)
