Auto-Sensing Rear Light G2 -Super Bright LED Bike Tail Light - Auto On/Off & Deceleration Flash by Motion Sensing - USB Rechargeable - IPX5 - Made in Taiwan

We use these for about 1.5 hours each night. They hold up well.

I'd say about 80% of the time I forget to turn on my rear tail light when going on a bike ride. I often forget to turn it off too until I'm home. This product solves both of those issues.Came in a nice package and looks to be built well. I tested out the stop-start lights by hand and it does appear to work well with little motion as described.I'm leaving it 4 stars for now for two reasons.1. It didn't come with instructions. Granted it is pretty simple to operate but a little mini page or two guide would be beneficial for people like me that may accidentally break a product while unattaching it from the seat connector to the clip. That didn't happen, the plastic is very sturdy.2. I haven't used it out on the road yet. If my friends say it works well behind me definitely will come back and give it 5 stars.Rechargeable for 90 hours is a lot of seat time too and no battery needed! Another nice feature.

After trying this light and others, we have decided this is the best light for us. It is easy to put on and has a variety of light patterns. The brake light feature is awesome and it's auto shut off is very helpful. It's not the brightest light out there, but does the trick.

It has different light modes, and theyre all bright. And then it gets brighter when it senses you slow down, acting as a brake light. Battery life seems to be very good. Some people say they are having trouble with the latch, but i have mine on my backpack and it works fine, no issues for me there but I could see where it could be more secure. Would recommend

Really nice brake light, especially liked the auto on/off and lighting pattern that changed as I slowed down. The only reason i don’t give it 5 stars is because the mounting bracket is awful. Nothing like heading out on a long ride and discovering mid-way that your tail light disappeared. The rubber strap was still wrapped around the stem of my seat, but the mounting system was completely gone.I am pleased to report though that I contacted the seller to convey my disappointment in the mounting system and they are providing a new replacement light.

I must admit, I was uncertain about this purchase. But the rear light does exactly what's promised. It turn on when it senses motion, and the lights get brighter when I slow down. Easy to attach ... easy to charge (though ( haven't needed to do so). This is a gizmo you can buy with confidence.

Loved how long the battery lasts on a single charge and it's ability to know when the bike is in motion. I have used it for about a month and still working on a single charge. I would have given 5 stars if not for the mounting bracket. The bracket would slip on every ride and the light light would face downward. I gave up trying to tighten and modify the bracket after many rides, and finally attached the light to a hose clamp as seen in the picture. Now all is good but a better mounting system should be provided.

Brake light is easy to install and so nice that you don't have to remember to turn it off. There were no printed instructions in the package but it's easy to figure out. It's bright and continues to flash until bike was stopped for just about 2 minutes.

Molto luminoso.facile da ricaricare.molto utile

This tail light is nice and bright but I think it is way too sensitive. The very slightest change in speed up or down and the brake-light effect kicks in. Thus making following traffic confused as to what the bike in front is doing. If the sensitivity could be altered this light would get 5 stars.

It is very simple to fit and the brightness is good but it's not very strong got the feeling it would break very easily.
