I just installed a The Box Light inside one of the hatches on my workboat. Designed for dark places on board that have no power source, the waterproof Box Light is from a company called Regarding The Outdoors. It provides a bright 180-degree beam via five LEDs. But it’s not just for boats. The Box Light can go under the hood of your car, under the trunk door, inside a toolbox lid; anything with a lid that you open and then need light to see inside. It’s powered by three AAA batteries (not included) and it turns on automatically when you open the lid you’ve attached it to. And, of course, it goes off automatically when you close the lid. Yes, I checked it out in the dark so I could watch it go on and off. But wait, there’s more! A daylight sensor keeps the light from going on when you don’t need it, which will help preserve battery power. At about 2.5” X 3.5” X ¾” The Box Light is compact and lightweight. I installed mine in under a minute with the provided two-sided mounting tape. Or can attach it with screws, which are also supplied. The light bracket is designed so you can remove The Box Light easily for hand held use. MSRP is $19.95.
