This solar powered LightCap from Sol Light is the water bottle with a light in the lid. The cap has a built-in waterproof solar panel , battery pack and powerful, long-lasting LED light. I guess the idea is that you will never lose your drink in the dark again.

With just a 4-hour charge of sunshine, the LightCap will stay bright for hours while the rechargeable Ni-Cad batteries will last for at least 300 cycles. Set it in the sun or hang it from a railing during the day and you’ll have light all night long!

There’s also a handy waterproof switch on the cap that lets you change from the white LED (bright), to red (preserves your night vision), or turn it off completely. You can leave the red light on all night (minimal energy draw) so you can easily find the bottle; then switch it to white if you need a light! $24.95.

And this gadget has also gained notoriety by being included as an honourable mention in TechEBlog’s Top Ten Strangest Gadgets of the Future.
