Read bike light + AirTag

As an ultra-long-distance cyclist, I was frustrated by my bike lights running out of battery mid-journey. The final straw came when the cops nearly fined me after my light lost power just 30 minutes before I got home, at the end of a 25-hour ride. That experience led me to build a solution with much longer battery life. I also used the remaining space to add an AirTag. For the mount, I used the one that came with the old light so feel free to design your own.
