The previously linked sets were smaller and perhaps easier to integrate into some tile work, but this version of the same idea comes in more of a standard brick size - and in the end, the more options the better, really. From the site:

Flush-to-the-ground, integral solar panels generate up to 8 hours of light each night. So guests can follow a cheerfully illuminated path to your door...Sun Bricks come on automatically when darkness falls, and incur no operating costs. Just recess them in your walkway, and forget them!

The SolarCap Lighting system consists of modular, self-contained lighting devices that can be used for decorative or traffic flow purposes -- powered only by solar energy. These unique devices incorporate the newest "EnergyCache" technology for energy storage, instead of the high maintenance rechargeable batteries that are currently used in solar devices. Unlike batteries which must be changed every two to three years and cannot tolerate environmental extremes, EnergyCaches enable SolarCap lighting to be used in any environment without maintenance for more than 10 years with a wide operating temperature range of -13°F -140°F (-25°C - 60°C). ]]> http://www.househacker.com/permanent/Outdoor-SolarCap-Light-Emitting-Tiles Gutter Stuff is a clever product that is so simple that it will leave many wondering how it was that they didn't think it up themselves. The product is a non-absorbent foam filler that fits in your roof's gutter, allowing water to drain out as normal while preventing leaves or unwanted debris from settling in.
