Review on 🚲 USB Rechargeable LED Bicycle Lights Set - LINE-120 Front and Rear Bike Light for Skateboard, Longboard, Road & Mountain Biking by Jacob Schmidt

I like it because it's small and light but seems to put out a lot of light when I tested it last night. Tonight I will go with him for the first time. I like it because I ride the unicycle to/from the office and can attach this light to the seatpost and point it perpendicularly in front of the seatpost. It has four "notches" for positioning the light so it can be aimed down at the floor or straight ahead (see image). (The other two bike lights I have are for handlebars, so mount them to the seatpost with the light on the "side" of the seatpost.) Here are a few questions and a concern. 1) 4 small "flashlights" in "corners" should the light shine? I did not. 2) What is a piece of styrofoam taped for? 3) I have a slightly scratched flashlight lens. I suspect it's the packaging as the lens is touching the plastic wrap inside the box.
