If you need to see where you’re going in the pitch dark, I really rate the Moon Meteor Storm, though it’s spendy
If you don’t need to see where you’re going (and they’re only to be seen by), then the cheaper Moon products are pretty good:

If you want something which will last forever and have a bit more cash to spend, Exposure have you covered:
or Alpkit (I have the rear light, it’s good):
I personally don’t think Lezyne’s lights are that great. Battery lights are okay but the USB ones I’ve had have always lasted about 6 months before the battery starts to diminish.
