375 nm UV Ultraviolet LED Flashlight Pocket size 1 AAA
$7.95
I purchased 4 different UV lights like this to try them out to check for fake ID's. This is the only on that worked. I will keep one of the other three to police my ferret's activities, and to check blood trails for bow-hunting, however the other two I will exchange for more of these pen-lights.

I bought this light to locate pet stains in my house. Standard alkaline batteries installed without any of the problems noted in other reviews. The light itself seems built preety solid and is very bright, capable of illuminating stains even in moderately lit rooms during daylight. Just make sure you're prepared for the disgusting things this baby can reveal. You can't un-see what this device will show you. Now onward to shopping for a good stain and odor remover. The horror.....the horror!

The light works but once the third battery goes in the cap will not stay on..I'm using scotch tape ..seems the pressure from the third battery is too great for the cap to handle..but it works..but at own risk

I almost blew a gasket when I saw this offered, in used condition, for $197! I get them for less then $10 each, and signed by 2 of the 4 authors. $197 is UNFATHOMABLE to me! If anyone wants one of these, e-mail me at D6RollingWay@earthlink.net !- Rich
