Sealed push-button switch
Standard handlebar mount
Frame Mount Lead Acid Battery
9 hour charger

NiteRider TrailRat @ $90 with:
6 V Halogen Headlamp
Tough, durable design
Sealed push-button switch
Standard handlebar mount
Frame Mount NiMH Battery
9 hour charger
Why the different prices? Other than the battery shape, they don't appear to be any different.
Differences are the battery chemistry. The NiMH is a more rugged, less delicate battery. It can be lightly abused, i.e. drained a little lower than optimal if you have to. It weighs less but takes more charge. The seal lead/acid battery is cheap, heavy and easily damaged.
Spend a little more and get the NiMH.
