Onvian Smart Bike Tail Light with Turn Signals, Rechargeable Bicycle Horn Bike Alarm with Remote, Auto-Sensing Bike Turn Signals Light Alarm

There are many similar combination smart bike taillight designs, combining some assortment of tail light, turn signal, brake light, horn, and alarm. There are quite a few direct clones of this design, as well, so it's hard to tell if this is the original or not. However, I prefer this Onvian model and have purchased it three times - for the original install to my bike, as a gift for a sibling's bike, and again after losing the original taillight in snow after wiping out (though, had I *known* I had lost the tail light, I reckon I could have sounded the audible alert to find it, so the onus is on me for not checking!).The Onvian smart tail light combines a number of useful features in a compact, light-weight, and frankly cool-looking package, and none of it needs some connected phone app to use - excellent! First it functions as a taillight with multiple modes and can switch between flash, pulse, and steady with a button press. It detects when you are slowing down and works as a brake light without needing to hook up to any thing else on the bike. It can signal a turn using the remote, likewise give an audible alert using its horn function, and the piece de resistance is that it can be set to work like a car alarm, with a single button press on the lock button switching the tail light from on, to off and armed, and a second button press on the lock button deactivating the alarm. It's all very intuitive and well-designed, and the remote comes with a handlebar mount so it can easily be snugged up alongside brake controls to make signaling and sounding the audible alert seamless. Battery life is good overall especially if the power-conserving flash mode is used. The remote also uses a standard coin battery style battery that is easily replaced.It has only one slight drawback and one possible drawback: when the battery in the light unit is low, it sometimes seems to have trouble receiving commands from the remote, however, recharging the base unit is usually enough to remedy this, and in case the remote is dead or lost, the base unit has a simple on-off switch built in. Second, I can't speak to how visible the lights are from a distance compared to a name brand like Blackburn.While Onvian now sells a model specifically for bike racks, this model can be readily adapted for rack use as well. In my case the rack had a flat panel for mounting lights that I was able to drill holes into spaced to mount this light.Overall, however, the sheer utility of this taillight outweighs any drawbacks it has.

A lot more nicer than it looks. Because it has loop attachments on the back, you can get pretty creative with how you can mount the light if you have zip ties. Out of all the ebike brake lights that I have tried, this is easily my favorite and best overall value worth. All functions work, flashing lights, turn signals, hazards etc. Battery life has lasted me about 2 weeks before I had to charge it, thought it depends on how long you commute for, and if you forget to turn it off or not. The active brake light does indeed work, very well actually. The unit itself is roughly 5 inches long in length, I wish it was a bit larger, but for my needs it will suffice. In, the future, I really wish they would release front turn signals with this brake light as well.

This light works as advertised. Although it's designed to be mounted to the seat post, I almost always have a cargo basket on my bike for shopping/beach trips, etc, and I was easily able to mount it to my basket. The sound volume for turn signals, horn and alarm are loud enough and also adjustable. I bought this for the turn signals and electronic horn, but also really like the anti-theft alarm. My reason for 4 stars instead of 5 is that once you attach the light to the mount it's not meant to be removed, so you either need to charge it while attached to the bike, or unmount and remount the light every time it needs charging. I cannot comment on the battery life as I haven't used the light enough yet to speak to that issue.

Absolutely love these lights! They work awesome, and you can pair more than one to the controller, and have front and rear signals. I wish they would sell them as a 2 pack. And with 2 alarms going off, nobody can touch it without you knowing. Extremely loud! Dash board control is removable and you carry it with you like a key fob. I also have removable pedals, and take out the battery and seat when storing overnight at campgrounds. Theives will find an easier target

The media could not be loaded. I love it. Works great with great range, I mounted one in front and back on electric unicycle.

It is very bright and easy to operate. I like that the left and right turn signals make different noises, but I agree with other reviewers' suggestion that the remote itself have some way of denoting which signal is on at that moment; I have not gotten a chance to test it on the road yet, and it IS quite loud, but I worry I will miss the sound with road noise. Plus I'm not sure I'll remember what side makes which sound. But it's nice, it's bright, it's a good size.My only real "negative" is that the bracket it comes with does not work on my specific rear rack. If I installed the bracket and light on the rack itself, the light would be upside-down. But I have a basket so I zip-tied the bracket to the basket and mounted it that way. Yay!
