It's not a dynohub issue, it's a judgment problem. Dynohub or no, you've have had lights if you hadn't decided to blow it off.

Yes, I have a dynohub on my primary commuter and grocery getter, which also has two battery headlights and one battery taillight. Belt and suspenders? You bet!

My other bikes each have, at minimum, be-seen lights permanently attached to them. Yet I don't leave the house without putting the MagicShine on them. Worked out today because I got the battery packs mixed-up and had no be-seen light for the daytime segments of my commute. (Well, as bright as it gets here on an overcast day.) Had the MS though.
