The patented diffuser, choice material & strict production of the full range grants stable and reliable performance, either by the lamp itself or indifferent work environment.
Not restricted to low input current, the full range safely supports high current charging up to 2A 5V, convenient to backup power at sources available.
Further for wide application with the enclosed changeable brackets, these lamps may mount on both saddle rail and round seat post. Q3 & Q1 may also fit to mount on the aero post.
Please refer to the specifications detailed in the graphics when you place an order. And hope you will find an ideal lamp in this listing.

A8 adopts the latest technology and combines full-round functions in one small lamp with both audio & visual warning, including braking warning, making itself one of the best and cost-effective rear lamps.
Optical Reflector. A8 has a unique dome-shaped reflector which is patterned in grids arrangement. Such special structure reshapes LED illumination for optimized visual effect while reducing direct dazzle to passers-by. The unique shape provides 200-degree wide scope visibility.
Smart Visual Warning. For regular rear visual warning, A8 has a remote controller to manage the lamp. More importantly, A8 features an accurate braking warning. The lamp illuminates at the highest brightness for 3 seconds when braking is detected. The auto & manual modes for options provide cyclists more choice to get the desirable use.
Wireless Bell, Remote Call, Burglary Alert. Press the controller key, A8 rings loudly, audible in heavy traffic. With the remote controller, it’s easy to find your bike in the parking lot. More importantly, A8 has induction or sensing to shock. When properly set, vibrations to the device will trigger off the siren and scare thieves away.
5V 2A Charging, 20-40Hrs Runtime. Priority given to electric safety, A8 supports up to 5V 2Amp input current, quicker for full charging, also safe to use with a wide scope of battery bank or adaptors, whereas cheap regular rear lamps can only be safely charged with limited 0.25-0.5Amp.
Water Splash Proof. Optimal design and careful production ensure water ingress sealing which is always needed for cycling in rainy weather.
Wide application. A8 has a dual mount system for seat post or saddle rail. With the quick-mount system, it’s easy and simple to install or take off. Both the brackets for the seat post and saddle are enclosed. No need to pay extra.

Hello! I am from Croatia. I am very satisfied with this alarm tail light. I put It on my Electric bike. It looks very nice. It is light and easy to recharge. The alarm od very loud. It atteacts attention of everibody in the street. Specially I like the thing that alarm is made in 2 phases. First it sounds as a warning sign when somebody touches my bike. If somebody holds iz for a longer time, then it sounds a very loud alarm that attracts people’s attention. The light is beautiful and it comes in four modes. When I brake, a special sensor within the device ignites a stop warning light. Once again, I am very satisfied with this product.

I order the second time with 2 remotes. This lantern will be a gift, as I really liked. Its smart functions with a stop signal are super, now without such a lantern I can not imagine driving (although there are analogs, but in this I liked the alarm function, it is very convenient when it is necessary to leave the bike near unattended). The only remote is very easy to lose, as it turned out, he unnoticed flew from me (though he drove around a lot). I recommend it to fix it more reliably, I will now hang it on the strap and clip it.

Had to write this as soon as i tried it out on my electric bike and installed it. The different light modes are very bright. The horn will get someone’s attention. The anti-theft device is louder than my truck and a very clear sound. I wasn’t expecting it to be that loud, I love it. If someone goes to steal your bike their in for a big surprise. If your just browsing for a anti-theft device with all these features. This is the one, you won’t be disappointed.

This light does everything I wanted and more. The alarm is useful to get my attention when someone tampers with my bike. I like the dual mounting options because mounting under the seat caused light to swing so I moved it to the seat post.

The tail light works fine it is visible and bright. What I really appreciate is the alarm. It is awesome and very sensitive. It certainly gives me peace of mind when parking in front of a store for a few minutes. When it is armed and someone touches the bike it sends a warning “chirp.” If it were moved it blasts a siren sound you don’t want to mess with. I’m very satisfied with this product!

Great product. Easy to mount. The honk works great but can scare people. It sounds like a alter alarm. It’s bright and works well. The motion brake light works great, and the alarm works really well.
