Bike lights are expensive. Mine advertised itself as waterproof to 50 meters (for deep sea biking?) and used a magnetic power switch to keep itself hermetically sealed. This promptly broke and rather that shell out another $20 for a new one I decided to bolt on a push button switch I had. I also have the habit of leaving the light on and draining the battery so I decided to use the opportunity to upgrade my bike to solar power.
I’ll admit it is a bit of overkill since the only power needs were my front and rear lights. With all this effort I decided to add on a USB port to charge my phone since I use google maps a lot during longer rides.
