If the walkabout in the park or garden needs highlighting, then try to get these solar bricks. They may not be the next best thing since sliced bread but they do cut it pretty close. There are no wires or power based problems, simply connect the bricks in the box on to the edge of the pathway or around the flowerbeds and there you go. The sun does the rest by charging the solar bricks who do their job by releasing this energy in the form of light once it gets dark.
