Solar spikes are set up and operated wirelessly. Simply screw the solar road stud butt light to the correct fence, path, staircase, wall, post or tree. Solar road studs are placed vertically or flat on the ground, and the screw holes are moderately sized to make the installation more secure. They are specially designed with road safety in mind, help prevent serious accidents and emit light instead of reflecting light. It works perfectly as a sun driveway marker to illuminate your driveway, and can also be used on docks, decks, paths, driveways, gardens, walkways, walkways, yards or patios.
