I came up behind a cyclist with a very bright standard sized light today, and as I drove by I think it was one of the newer Hotshots. I see they have a Pro 150 now. I'm going to pick one up.

I've owned a DesignShine in the past, and sold it because I think that it really is kind of overkill and it goes through batteries very fast. I'm running a Danger Zone down low and a Blitzu 168T on the helmet currently. I'll probably put the Hotshot in place of the Blitzu - it seems to not have lasted long, the battery dies quickly now.
