Review on WSDCAM Smart Bike Tail Light With Turn Signals And Brake Light, Bike Alarm Horn With Remote, Auto ON/Off Rechargeable Waterproof Bike Horn Alarm Rear Bike Brake Light Turn Signals Bicycle Tail Light by Todd Stone

This is a combination bike light.It has a number of different functions:1. Multifunction taillight2. Vibration sensing alarm.3. Brake light4. Turn signals.The taillight has many different states such as blinking, breathing, fast blinking and a couple others. It has an internal battery that is charged via the USB C port.The alarm is armed using the remote that you carry with you. The alarm will go off when it senses too much vibration which may happen if somebody tries to steal your bike. When you are riding the bike, you insert the remote into the holder that is mounting on the bike handlebars. This allows you to use the other features like turning the light on and off and using the turn signals.I don't think the brake light works which is a bit of a shame.Installation is fairly easy. You just attach the light part to the seat post using the clamps. I would have preferred to mount the light somewhere else, like on the rear rack, but no hardware is provided to do this.The mount for the remote clamps onto the handlebars, but my handlebars are too thin for the clamps. They should have provided some spacers. I tried making some homemade spacers, but the problem is that it takes quite a bit of rotational force to insert the remote and because of the force, the whole mount tends to move. Maybe a hard rubber spacer would work.There is a horn that works but with a slight delay when you hit the button.Otherwise, I think this is a useful bike accessory
