These cool new Magnetic Umbrella Solar Lights ($40) are durable, weatherproof lights that have two halves held together by powerful magnets. The top half has a crystalline solar panel that charges even in cloudy weather and the bottom half has 4 super bright LED lights that run for 5 hours on a full charge. They easily attach to patio umbrellas, awnings, canopies and other cloth surfaces with ease. If you really want to light up the night and enjoy those warm summer evenings out on your patio, this is a perfect solution. (via Michael Kiely)
