I'm sure it'll work fine. I have a set from a different company, Niterider Lumina 350/500, is the model, I believe.

I like mine because it's bright, charges with micro USB, and I keep it in a bag on my top tube most of the time. My light has a very similar mount to the one you linked, and I do have some issues with it: The front mount rattles, just enough to be annoying.'

I experimented with a Cree headlamp a few months ago, and I've been nothing but pleased. If I were getting an entirely new setup for myself, I'd be very confident spending a lot less. Rear Light I've been looking at.

Front Light I've been looking at

The other thing I've been thinking about is using an old/functional battery/solar cell combination with this head light. Cheap, because it doesn't include a battery, but it would work for my commute rather nicely.

The awesome aspect of the kit you found is that it's entirely removeable, and quickly. If you're leaving your bike outside, you don't have to worry about the lights walking away on their own. I leave my mount attached, remove my light, and I'm set. When I reattach, the light is already calibrated, adjusted and great. The headlight I linked to wouldn't be able to do that, you're have to remove the entire system every time.
