<p>I bought my D a clip on book light that runs on AAA batteries from Bed, Bath, and Beyond. It was about $10. Then, I saw the same type of lamp that had an even longer adjustable neck to it. Can’t remember which store, but I am sure an internet search would work. The light we bought clips onto the computer, or directly on the book you are reading, instead of to the bed itself.
You could also use a strong, sticky hook on the ceiling, and hang a lightweight light on the hook.</p>
