Solar garden lights are designed to be shoved into the dirt along a sidewalk path, like spikes. I wanted to illuminate the stairwell of my rock wall, at my Civil War-era farmhouse. This shows how I did it, with cheap, but bright Westinghouse solar lights - $4/each, at Wal-Mart.
Step 1: Remove the rod on the bottom
This is one of those $4 Westinghouse solar lights. You don't need the stake on the bottom, just the top part, which contains the solar cell, battery, light and lens. I had to doctor the picture below - basically remove the stake and save it for something else.
