Poor quality product

I purchased a few of these lights and they all started to play up. One of them did not work straight out of the box, the other two I got started playing up after a few days. The on/off button on them stopped working properly. They were inexpensive so I could not be bothered returning them but I would deffenetly not recommend them or buy them again!

LED Bicycle light Red or white

Most easy to install, options for flashing or continuous very good, intensity to be seen: OK for 300 yards - Too early to comment on battery life

Hello Juan, thanks for your detailed review, we so appreciate you taking the time to write a product review with us. We hope to see you back on soon!

Good visibility light

Some extra security for City rides. Every little bit helps. I coupled them colour with some of the fluorescent green socks. Got a few comments…..but….they noticed me so that’s the point!

Simple, small, bright

Battery powered light, very bright, easy fit to bike. Mine fit into under seat bag (on side strap!) as additional light. Battery life unknown. But they are easy to replace, and not expensive to buy in multipack in many stores. Recommended in You need extra light.

Super cheap backpack marker

Bought for attaching to a backpack for night walking. Super lightweight, simple and cheap. Battery small but easy to replace. Attaches easily to Molle or straps with its rubber loop. Excellent.

All weather light

Bought these for my dog's lead and harness and I thought they were pretty good until I accidentally left them on a muddy harness and put them through a 2h 38m 40-60°c wash. Now I think they are excellent as they still work!!!!
