Hey everyone:

I'm looking to buy another set of front and rear lights for my bike. The features I'm looking for are:
- User-replaceable batteries for both lights
- USB-rechargeable
- Lights can be detached from the mount when leaving the bike unattended for a while
- Handlebar and seat post mounts

I don't need lights that are so powerful that they will blind oncoming cyclists. 400-500 lumens should be plenty powerful enough.

Are there any particular brands or models that you all would suggest? I have sifted through some of the stuff on Amazon and haven't yet found anything with user-replaceable batteries. I would like to buy a set that is going to last me many years of riding.

Thanks!
