I can't say much about the rear light - I built my own out of automotive LED lights before hearing about the Phillips (See total geekiness, near the end these days). The front light is a nice light, which I just retrofitted with a 5V regulator (ibid.), though I haven't gotten to ride it yet. I like the shaped beam, though I would like even more light, especially for those times when there aren't cars around. Thinking about building a narrow beam light to aim at the end of the LBL.
