NineLeaf Smart Bike Tail Light with Turn Signals, Anti-Theft Bike Alarm with Electric Bell Automatic Brake Light,Remote Control Rear Light USB Rechargeable Safety Warning Cycling Light IP65 Waterproof

I bought it for my new e-bike that has a front light but no rear light. The product works very well and has many different functions: turn signal, loud horn of 3 types, alarm, automatic brake light, and various running light modes, also a flashing light. The number of signal groups it has is really surprising. It charges with a USB C port and the duration has not been checked yet, but I think that for the price it is an excellent opportunity, I recommend it.Please read carefully the instructions before using becaise is to many functions.

Update #2: I recently bought my 4th one. However, during a crash, one of the key fobs lost the button that sets the alarm. I can't seem to find a way to contact the seller to see about getting just a replacement key fob.Update: I have now purchased three of these for three different electric bikes. I've also recommended them to at least a dozen other people. For the money, these are about the best thing you could put on your bike.This thing does so many things, it's a little unbelievable. Taillight, brake light, turn signals, 4-way flashers, horn, and an anti-theft alarm. Plus it has a great little key fob that you can easily dismount and carry with you. It's designed to only mount on a seat post, so I had to fabricate a way to mount mine on my cargo basket. Also, the labels of the otherwise well-designed buttons on the remove/key fob are black-on-black so they're hard to see at night. Overall though, this is a must-have.

Works well over all, plenty bright. I got it for mountain biking which was a mistake. I wanted those following me to know I was braking but over rough terrain the brake light comes on all the time. So this is really only for street use. And the alarm is way too easily accidentally set.

I’m quite impressed with this tail light/ Brake light/turn signal and a bike alarm that actually works. I feel so much safer when there’s traffic behind me and I need to slow down or turn. The turn signals do make a clicking noise similar to a vehicle. At first I didn’t like the noise but it’s put there for safety, to get motorists attention. After using it every morning and afternoon on my commute to work and back it’s nice to have.Plus, i have a reliable alarm that has the right amount of sensitivity and once the tail light is installed it’s designed to be time consuming to remove. Along with an AirTag hidden on it, I can not lock my bike up and be confident it’s safe. I definitely recommend this to anyone that rides a bicycle. Well worth the money ⭐️⭐️⭐️⭐️⭐️

This is a great product especially it being wireless. The best thing I like about this procuct is that when you push the turn signal button, it makes that signal light sound. When you hit it again, it stops so you will always know if it's on or not.

I bought one September 27, 2024 and it fell off after 3 months. I bought another at the end of December and it just fell off. This one didn't even last two months. The bracket is poorly designed and doesn't seem to handle bumps very well.

I love this light easy to install. Works well. I especially like the alarm feature on my e-bike. Keeps people from messing with my bike and distracts thieves.

Product seems good; however, I am missing the lug nut. I installed it properly (the oval remote was my option) I charged it before first use and noticed that I am missing items. It may not be a big deal but for the sake of it. It might be before it comes with the exact number of tools or extra pieces. It came with 3 lug nuts and I needed 4.
