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

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.

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

All the light patterns are great, the different audible beeps from the left and right signals are very helpful, very bright at night, the different light modes are excellent, just make sure the alarm is off when you charge the light. The alarm WILL go off when you disconnect the charging cable from the light if it is armed. Oh and it's LOUD!!!A little tedious installing it, I had to move the power unit to make room for the remote and the small nuts and screws are somewhat difficult to install if you have shaky hands but that's my issue, a breeze to install if you have experience with Bikes, you could do it in 5 minutes or less.Overall I love it, I feel safer riding on roads with traffic and other bikers. Definitely worth buying it if you ride the streets!

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.

I got this on sale and couldn't be happier. It's the perfect solution. Turn signals, brake lights and alarm system. It's super loud.

This was better than expected. Function remote response. The alarm is pretty loud. Installation was a bit challenging but with some patience we figured it out.

UPDATE: Original still broken but I was contacted by Onvian, the seller, and they have shipped out a replacement as it was under warranty. I updated the review based on seller's quick response. I hope the new mount lasts longer.I really like the light and its features once I figured some of them out.Attention-getting to my friends, one of whom enjoyed the "brake light" feature.Alas, my days of using it appear to be over as the very robust-appearing mount broke as seen in the photo. It was affixed securely but I noticed it rotated on the mount. Then I realized it was broken.I will approach the seller to see if there is a warranty that will make me whole again on this. I don't know that the mount can simply be replaced as the way it is attached to the mount it really isn't removable without unscrewing it, a small drawback to me, although for certain an anti-theft measure. I had to bring the charger to the unit rather than having to unscrew it to take it off the bike.I don't really know how to rate it fairly because the light works fine but I don't know how to attach it so it's like I don't actually have it any more. So for now a 1 because it is unusable after less than two months.

This is an amazing deal. It gives you turn signals, brake lights, and a horn plus the super loud alarm and key blfob.
