Yes, the beam is pretty narrow. I use mine on my helmet too, but got a much brighter light (Serfas True 500) for the handlebar. The Blaze 2W as a helmet light works well for alerting motorists to your presence, but I don't think it's enough for general lighting. The Super Flash mode is very eye-catching, but I usually use it in the higher constant mode.
