I think so. I have two headlights on my bike and one on my helmet. Also have four tail lights. All are battery. One time, at night, in the rain, all three of my headlights died. The spare rechargeable AA batteries for one of my headlights were even dead. I made it home safely, but it was a bit "exhilarating".
I've contemplated a hub light, but now I just check my lights after I ride so I don't leave a dead light (or three) on the bike.
