Ampulla Motion Sensor Bike Taillight USB Rechargeable Ultra Bright Bike Rear Light Fits On Any Road Bikes, Helmets, Cycling Safety Flashlight With Brake Sensing

Visible, easy to mount, lightweight, chargeable

very good light , the only bad thing is that the battery only takes very little, but I am happy, I would definitely recommend it to my friends

Idk where ppl are saying its 5 stars. It is Bright and it works, yes. It charges and seems to be made decently. The mount is firm and made of thick decent non scratching rubber. It does the SOS 45 degree angle thing. It has bright and dim settings and the three different modes. So why do I rate 2 stars? Because the motion sensor doesn't work right so it is ALWAYS on brake mode. Once in a while it'll flash on the mode it is supposed to but it doesn't detect speed decrease or increase. It just always stays in braking bright light mode. Not actually bad in low light conditions but it isn't working as described or intended.

Fast shipping in great condition works ,,,but ,,ai needs more work motion sensor works poorly normally won’t work unless it is jiggled so peddling doesn’t do it rolling is out too so try a little more and you could have a great thing

I have bought this brand of light last time and it has very good quality. Although it is different model, it still impress me that the light is very bright. Very easy to install, just hook. I will highly recommend this for biker. Let’s ride with safety.
