Review on 🚴 OTYTY Bike Tail Light with Turn Signals | USB Rechargeable, Ultra Bright LED Safety Warning Brake Rear Lights | Wireless Remote Control | 4 Modes | Waterproof | Suitable for Mountain Bike, Road Bicycle by Michael Copeland

I added this to a power chair that was being used on the road by an elderly and very stubborn relative (ugh!). I was able to install it using the material that came with the unit. He likes the remote control and especially the turn signals. I'm sure no one has any idea what direction it's signaling, but as long as someone sees it I'm happy. It's bright enough to get the job done. He has no problems with charging or the remote control. Almost 90, the "on/off" switch on the back of the light block confuses him, but that's really outside of the design of the block so it's unfair to vote for it.
