Consider using 4-watt mini-fluorescent or electro-luminescent night lights. Both lights are much more efficient than their incandescent counterparts. Also, the luminescent lights are cool to the touch.
A hot glue gun can provide an alternative when labeling containers of small parts. Glue a sample of what’s inside to either the top or sides and you will immediately know which container to grab. Whether you use the glue method, labels, or just write on the container, repeat it three times equally spaced around a can. For square containers, identify all four sides. That way you will know the contents regardless of which way the container sits on the shelf.
