DUO-120 Rear Bike Light – USB Rechargeable Red & White LED – Flashing Strobe Tail Light for Bicycle Safety – Adjustable Angle for Seat Post, Fork, or Seat Stay [New 2025]

I am not sure what else could be done to improve these. They're essentially perfect. Bright, long battery life, easy on/off, seemingly perfectly waterproof. They're just exactly what you want them to be. These are the bike lights you want to pick

Wow those are the best very bright different modes don’t settle for cheap stuff pay little bit more and get those

they work very well

Lumen brightness is exceptional for such a small light with a wide variety of lighting choices. Would prefer the standard solid square strap insert rather than the round insert that came with it.

These lights are easily noticed when flashing alternately between white and red like strobe lights. They last for a long time and are easy to take off and recharge. The only issue is that eventually the charging plug on the back comes loose making it impossible to charge them and I have not figured out a fix for this yet aside from buying a new one.

They work really well and the battery lasts a long time.

Bike light is super bright and has a few settings. Charge port is the old USB and not the newer USB-C plug.

This is a great product. It easily attached to my bike structure and was/is very, very visible. I didn't see operational instructions but quickly went through each light sequence, then discovered simply holding down the button thatchanges the light mode also shuts if off. I am please with this purchase-"you won't be disappointed"!
