When I was little I remember playing with my father's Diagnostic Pen light while he was working on cars.
I didn't really think of them being used for Medical reasons but now that I am older and have seen them used that way it makes sense.
These are great penlights that come with batteries, have the measurements on the side which my father's did not have, and have a click on/off feature instead of having to hold down on the metal clip.
Can be used for many other things besides the medical and auto fields.
You can purchase the ZITRADES 2pcs Diagnostic PENLIGHT on Amazon.
