If you’re looking for a novel way to illuminate an outdoor space, these tiny, waterproof, and practically indestructible LED lights are perfect for sprinkling about your yard or submerging in a pool or creek.

Steve Hoefer likes to wander the hardware store, looking at various parts and day dreaming of future projects. In this case, the future project was a pretty clever design for LED lights. He writes:

Some things just seem useful, even if I can’t think of how at the moment. One time I found matched pairs of PVC caps and plugs that fit together into little airtight pods of various sizes. For what, I didn’t know until I wanted a way to float lit LEDs down a stream.

The result: simple, rugged, floating LED lanterns that glow for days. They’ve survived being submerged for a week, frozen, and laundered in the washing machine. I even hit one with the lawn mower, and it still works. When they get dirty, just hose them off.

We’ve never wished so hard to have a pastoral looking creek in our back yard to fill up with cool LED lanterns. Hit up the link below to check out his build guide and crank out a few of your own.
