Rechargeable lights front and back. Both are bright and certainly last my day. I recommend a daily charge if you use it for more than a few hours in a day. My one real BUT is the rubber tab that is inserted on the red rear light. It is a total pain in the butt to get that piece out every time to charge. I have to use a pointy knife to gain access. It's a good seal, but man its a challenge to do it with my fingers. The other thing for the red one is that it is tough to connect to the charger for some reason, I think it's maybe sitting wrong in it's place or something, just not easy to charge. So 30 bucks for both of these you can't beat the brightness and the convenience of these lights. If they last, even better. Change that tab!
EDIT UPDATE AUGUST 2021 I have actually upped my rating from 3 to 4 stars because I really like how bright the front one is. I don't use the red one anymore. I hated spending 5 minutes to try and get it on the charger plus it wasn't that bright. But I do like the white light. It still works but now I find it may last about 3 hours and sometimes I go for longer. So I'm just going to buy another one. Compared to many others out there, this one still shines through for price and brightness. Stay tuned.
