That's a good idea, and while you're at it buy a small bottle of silver nail polish. The digital tach reads the reflective "special" sticker they include. When those stickers run out, silver polish does the same thing for a negligible amount.
I also have red and green nail polish in my stash. The red paint is for those stupid little arrows on bottles you're supposed to line up to open. Well, without glasses the dot (where they meet) is all the help I need.
Ditto on USB plugs. Top has a dot of silver polish, or red as the case may be. I have a code...
Tachometers are handy, and so too are infrared thermometers. They've come down in price too.
It's handy to know how hot various spots are on your engine. When you do your engine room check, shoot the motor. Suggested spots include injectors, alternator, fuel pump, manifold, risers, etc.
Things do not usually "suddenly" break. There's generally been a problem unseen that develops and then: BANG. If you know how warm your fuel pump is usually and now are seeing ten or twenty degrees hotter, well, that's something to troubleshoot before it breaks, eh?
