Whether you just need to see the keyboard in dim conditions or don’t want to disturb your wive while watching television, this little gadget can be a lifesaver in many situations.

Someone in IT support, for instance, will swear by it. One of the worst parts of the job is having to get down on your hands and knees to wriggle underneath a desk to retrieve or replace a faulty desktop tower. It’s demeaning, always dark and dusty, and – probably because you chose the way of least effort the previous time – going to take you a while to figure out which cable goes where.

While this gadget won’t solve the problem of having to crawl into tight spaces, it can help you plug in a cable in less than three tries. It’s nothing complicated, just something that allows you to power a bright LED from any convenient USB port. This makes it great for seeing behind computers, and you can also connect it to a laptop or power bank to make a kind of reading lamp.

At almost 10 inches (minus the connector and light), the cable could really be longer. It does, however, make this light small enough to stuff into a shirt pocket or laptop bag. It’s also rigid enough to stand on its own and keep the light pointing where you want it.

People who need this in their lives won’t ever want to be without it again. Others will plug it in once to see if it works and then forget about it. You’ll already know which kind you are, but if you have a harassed-looking computer guy in your life, take a moment to consider buying this for him. It saves more frustration than you can possibly believe.
