I use a cheap USB recharageable rear light from Amazon which have worked great and are nice and bright. For the front light those don't work so well if you need to illuminate the road ahead (rather than just be seen by others). I use a LifeLine pavo 720 lumen light which has been great. I don't think they sell that particular model any more but something like this is very close.
