It doesn't give any sort of warning before the battery goes dead. Something like a low-power 3 color LED as on Magic Shine lights would be great, perhaps only active when it's turned on so it doesn't eat batteries when not running.
I keep a spare in my commuting pannier so I'm not unpleasantly surprised.
