Review on 🚲 JIAN BOLAND Smart Bike Tail Light: Turn Signals, Anti-Theft Alarm, Brake Light - Waterproof & Rechargeable - Easy Installation by Dale Rylander

I'm amazed at how useful this bike light is. It really is SMART. I won't duplicate the features already mentioned in the description but I want to say that they work. 1) Especially when braking, the red light will be brighter. 2) The turn signals are bright and the sound is audible enough to warn. immediately surrounding traffic / people. 3) The anti-theft alarm system is also extremely useful and works as advertised. I charged the device overnight, the only problem is that when I plugged it in to charge, the light stayed on all the time. It's not necessary, but I don't care either. I was able to attach it to my bike fairly quickly and easily using the supplied screws/bolts and wrench. I wasn't able to do a full usage test to see how many hours a charge lasts. But I will update this review accordingly. If you are a cyclist and have never had a light attached to your bike and you ride late at night. IT IS NECESSARY. This is life saving.
