VICTGOAL USB Rechargeable Bike Light Set - IPX5 Waterproof Dual Front & Rear Bicycle Lights for Road Cycling | Perfect for Night Riding, Commuting & Mountain Biking Safety

Front & rear lights that can also flash for use on my Bike or Helmet.I've been using this light every day for almost 2 years. In the pouring rain, snow, baking sun. Flawless. Very bright. Lights my path much better than my expensive front mounted bicycle light. Cannot recommend highly enough.The light fits great on the helmet and it seems to work well - nice way it fits on the helmet. BUT, it is not 400 lumens. it is 100 lumens. I picked this one over another one because it was 400 lumens.It is an effective light. I mounted it on my helmet. But the battery life is poor, barely lasting three hours on the blinking mode.ExcelenteThis item doesn't attach to anything. The design is such that the wrap doesn't attach to anything, not even back onto itself! It's useless.This light can be mounted on your handlebars, helmet, or seat stem. I chose to mount on my daughter's handlebars and we only use the flashing white light. It can use simultaneously turn on red and white light and have them both steady or flashing. It's very compact and versatile. I would consider this to be a "safety light" and not one that you would use in the dark to illuminate the road ahead. On the plus side, it adds very little weight to your ride.Pretty bright light. My daughter in law enjoys riding her bike to work(. Its 1 minute away if shes drives)This provides her with proper lighting for people to see her and use caution..Its good for her to have a light that leads her home saftely .. Happy with this purchase
