Kevin sent in this neat bicycle light made from a recycled Parmesan cheese container. This would make a great addition to a lot of the DIY bike lights that we have featured on Make. [Thanks Kevin]

This page describes the construction of a universal bike light battery with eight “C” cell rechargeable NiMh batteries. It is made from a Parmesan cheese container which is strong, lightweight, splash proof, dust proof, fits in a water bottle cage, and allows for complete serviceability of the batteries. High performance NiMh cells can raise the capacity of this unit to as much as 10,000 mAh.
