Other 'feature' that one of them has is it doesn't strobe, it just flashes like a regular blinkie light. It still seems as bright as the one that strobes though. It's the strobe one that plays up in the wet weather - the other may too but I don't use it much as I prefer the strobe, it's used mainly as a spare or as a supplement (put it in the rear jersey pocket).
I took one apart before I posted, and the seal is kinda of difficult to notice as it's attached to the body of the light. Mine is a Plant Bike one though, so perhaps it is a Smart/PB thing.
