The moon nebula for a rear light is great - battery life is excellent, it has a day running mode, and can also be super bright if that's ever needed. The clamping mechanism also makes it really easy to take off quickly and fit any awkward shaped seat posts.
In terms of front lights, cateye lights are good quality but rather expensive if you want something that will light up the road.
EDIT: I think a pair of the nebulas will be perfect for what you need
