Tiny DIY Waterproof LED Lights Perfect For Summer Parties

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.

If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). You can follow him on if you'd like.

    I’m new to wiring but have done basic soldering and could handle a design using basic resistors/capacitators/whatever else I may need.
