I Use the PB superflash stealth, and it is definetly a good taillight. I also have a Mars 3.0 kit I believe. The kit came with a head and taillight. I think I picked mine up at Dick's Sporting goods or something like that. I purchased the later before going with the Superflash. Compared side by side at night about 100 or so feet away the Superflash was definetly brighter (I work at night). I picked up the Superflash because of suggestions by others and I can tell that light apart from others I see.

The headlight with the Mars is only good if you ride on well lit streets and like others said, its more of a be seen type light. The 3.0 taillight should be fine though, mine worked for the year I used it before changing over. I think most people think highly of the taillight considering the price. Headlights are another issue all together though. You'll read alot about the Fenix lights (I have two O-lights). They really are a multi purpose type light though, and not necessarily bike specific. You can buy the twofish lockblocks to mount most of the Fenix flashlights. Check out the Fenix Store for ideas.
