wsdcamSmart Bike Light with Turn Signals, Brake Light, and Alarm Horn - Auto ON/Off Rechargeable Waterproof Rear Bicycle Tail Light with Remote

Easy install, good value, hardly needs recharging, and visibility is great as traffic clearly abides by my turn signaling. It has additional features such as theft alarm when the bike is parked and the handle bar module is quick release. It's literally a perfectly designed product, I love it.

I have had this bike tail light for one year now. Even though I use my bike and the light seldom, the battery on the light lasts a very long time, which is great, because it does not detach from the bike easily and therefore, in order for me to charge it, I must either unscrew it to remove from bike or take my charging cable with extension cord to the bike and device. I have only had to charge it 3 times in one year, awesome, except on the third time it would not recharge. I have used it approximately 200 minutes in total over the course of 1 year and it already needs replacing. I keep my bike indoors at all times it’s not in use.Pros: works great, easy installation, sturdy parts, bright lights, great functions, works seamless with blinker, maintains a very long charge.Cons: The devices battery only works for approximately 200 minutes, leaving the product useless, charging is not as easy as it should be, device is quite expensive for the limited time it works.I have contacted the manufacturer with this issue and will update this review with the outcome.My recommendation:Prior to knowing how the manufacturer resolves the issue: waste of money, buy a more reputable brand.After the manufacturer attempts to remedy the issue: TBC.2/27/2024 - UPDATESo, I never heard from the manufacturer, which is disappointing. However, it turns out it was operator error! I decided to try and charge it with a different cable, one that wasn’t as powerful, and it works! It charged and it works great just like it did before so I’m changing my review from 2 stars to 5 stars. Based on the fact that customer service never responded, I could easily remove one star, but considering there was no problem to begin with, I will give them the benefit of the doubt. This is a a great product! And, a life saver, if you’re a night rider, like me.

So, I am pretty pleased with this. I like the various modes of operation, the "brake light" effect, turn signals, horn and alarm. Battery life seems great - haven't recharged it yet and have used it for several rides over several weeks. I'm hoping I'll know when the battery needs charging before it goes out.But I do think it could be better. If I could change it, here' what I'd suggest:1) I think its great to include the "Emergency Flasher" mode of operation, but this is selected by scrolling through the different modes of tail-light operation. While riding, you have no idea what mode of operation the tail light is in so unless you stop, get off your bike and look, there is no way to use this mode. The solution is rather obvious - this isn't even a mode of the tail-light - it is a mode of the turn signals, so activate it by pressing both turn signals buttons together and indicate it is on by alternating the 2 different turn signals sounds. Turn it off the same way.2) as noted above, there is no way to know which mode of operation the light is in - or if it is on at all. Including a sound when the mode is switched seems easy. Even if just a beep when it turns on the first mode would provide some clue.3) The "Automatic Mode" should be separately selected from the light mode. I like that it turns off after a while so I don't forget to turn it off. Though I worry it might be turning off while I am riding and I want my light on at all times - not just after dark.4) I notice the remote has an unused "front light" button. Is there a front headlight that can be controlled by this? That would make a nice pair. I would especially like this if that front light included turn signals as well since I am finding I still need to use my hand signals for the oncoming traffic.

Great addition to my recumbent bike. Being low to the ground, it is important to have motorist know where i am and where i intent to go. That is what is item has done. The blue tooth connection is a game changer for me, which gets rid of any wires from the old days. Easy to install and works great out of the box. The alarm system is awesome.

To put it simply this is just a great product. Excellent battery life, great features, well designed. It's just really good. Highly recommend. The lights plenty bright, signals work good, signals even make different sounds depending on direction and a red or blue light comes on depending on direction on the remote, remote can easily snap to bike or be taken off, sounds can be customized, I can keep going but this really does have all the features I could want in a bike accessory. Very well designed!! The only improvement I could ask for is that the volume of each function be independently adjustable as I want the alarm very loud but don't really need the signal sound and horn to be that loud. Minor complaint tho for a great product!
