We discussed the small LED flashlight that Harbor Freight sells and gives away on coupons.
I noticed that a couple of them went dim, so I pulled out the battery cartridge and tested the batteries, which all tested normal voltage.
Then I pulled the batteries, took a small pick tool and pried the + contact out just a little to make sure the batteries were making contact.
With 3 batteries making contact, the flashlights are now as bright as they are supposed to be.
