Let’s say you need to look at something in high-end detail, but it’s in a tiny corner of your car/truck/garage — and you need a light, too. Now you can accomplish this with a single tool: Moroso’s lighted magnifier. It’s a flashlight that provides 3.8X magnification.
You may laugh, but this looks to be perfect for identifying spark plug problems.
