Review on 🚲 800 Lumen Rechargeable USB LED Bike Light Set - Tesecu Rear Bicycle Tail Light and Front Headlight with Bicycle Speedometer Odometer for Mountain & Road Bikes by David Batte

Light and horn work great. I set up the speedometer as instructed and it gives me a reading, but the speed reading jumps all over the place and never shows a consistent reading, so I can't trust any of the distance information either. I've added a video to show the discrepancy in speed measurements. Edit: The connection to the horn is via the micro USB connector. It took a day before the end of the cable finally broke off. Now I don't even have a horn. An offer to an engineer not living in the real world. Connect the horn wire of the same type as your speed sensor or similar. There's a reason people keep buying new charging cables, it's because those damn connectors break so easily.
