Smart Bike Taillight w/Seat Post Mount: Auto On/Off w/Motion & Lighting Sensing; 3 Flashing Patterns for Auto/Manual Mode; Deceleration Warning Light; Low Battery Warning

I used two of these on my electric skateboard. They look really good and the battery lasts for hours. I'm not sure why people are commenting on the brightness level, they seem plenty bright to me. They are weather sealed so they survive wet conditions and they are easy to remove from the mounts they come with. Highly recommended.

Of all the rear tail lights I’ve been through, I really like this one the best. Mounting is simple. The light lasts a long time. It can be switched from “manual” to “auto” so that it only comes on at dusk with movement, thus, saving the battery. This is small but very visible for its size. Having said all that, I don’t believe this works like a brake light of sorts, as advertised. It’s hit or miss. Still, a great light.

I started with more expensive lights - and they never lasted - mostly they fell off while riding, but some just quit working. Sometimes I have gone years without a tail light because I had such bad experience. So, I look at reviews and I look at the mounting mechanism to decide if I will buy a bike light. This light is about 1/3 the price of others I have had and the quality is as good, and of course it has the best mounting I have ever had.

Good back light I have it installed on my dirt bike and it works very well u can see it in the morning as well at night when u brake the light gets brighter to show that it’s braking no wires need the only reason why I gave it 4 stars is because the instruction manual isn’t that clear.

It was bright, and then it was dead, in less than 6 months.

Was looking for a tail light and I found this to be interesting. Neat design in compact shape with metal touching match my sleek bike body. Also Weather resistant. Easily tight and hook rubber band brought in convenient installation way. Auto break light function protect and remind coming vehicle my existence in the dark when the bike movement slow down or stop. Auto start and stop is really great design for away from light switch on/off headache.Its so compact, I can use this for my hiking pole. What can I say, Its multi-functional. 2 thumbs up.

Previously had a niterider taillight mount snapped on my mtb. Love the way this light mounts tucked under my saddle it does not interfere with my seat dropper post. I carry my backpack so I'm not concerned with tool bag on my saddle. I usually leave it on auto mode when the bike is parked it turns off automatically. Battery life is awesome sometimes for weeks I don't charge it. Highly recommend this light :)

Love it! I bought the one with seatpost mount because I have a seatbag under my saddle. Auto and Manual mode work great, easy to install and just unscrew the light from the mount to recharge.
