I use to have a Power Beam 5 led light mounted on my helmet held with rubber band. It worked well to get attention. After I got my MS light, I continue using it on my helmet until one day, my battery died because I forgot to charge it. I now went back to a P7 which is a overkill but it serve as a backup when needed. If anything, I thought about mounting the P7 on my handlebar next to my MS light and go back to the Powe Beam on my helmet, but the super bright light working along with my MS light works so well that I don't think I'm gonna change that.
