Thank YOU! I spent a LOT of time on the internet trying to find what was in the Japanese picture. No one had exactly the part pictured. What you found comes closest. THANKS for reading my post and working on it!
I'd like to have a firsthand look at it. How can they power bright enough LEDs with solar power in such a tiny package? Yes, I know, there's probably a small battery, but how long would that battery be able to power the LEDs in the city at night with lots of turns? But if it works, I might be interested. Depends how effective the wide angle mirrors are and how they interfere with the regular mirror function.
