Whether you’re an audio engineer, an IT guy, or just a regular dude with a computer shoved under your desk, eventually you’re going to have to crawl into a tight, dark space and try to fix a wiring issue. A TV-biz friend of mine recommended a much better solution: slap a stick-on light under that desk or console before crunch time.
The one pictured above — the LED-based DOT-It from Sylvania — is my favorite, though you can find similar models everywhere, from your local big-box to late-night TV infomercials. The DOT-It delivers a claimed 100 hours on three replaceable AAA batteries — enough for many, many cable swaps.
The bottom line: the $5 to $9 you’ll spend on one of these will keep you from crawling back out from under the desk to go and hunt for a flashlight many times over. You’ll completely forget about it until you’re already down there — where it’ll be there, waiting to make the difficult simple.
