You’re working on your car and .. there you go.. that screw / washer etc. is falling down.
You’ll have two problems..
1) You don’t see where it went as in most cases it’s dark
2) You can’t reach it!
This Flashlight makes life easy! Simply turn on the light, extend the magnet bar and point it to where the screw fell. If it’s metal.. you’ll have it. If it’s plastic… well.. you can at least see it.
