Keychain lights are handy no one will dispute. However, you may ask what use would an ultra violet or UV keychain light be? Well there are many. What seems to be popular now is using them to detect ultra violet inks and markings in documents like drivers licenses, credit and debit cards and currency etc. They are used by employers, bank personel, bar and security personel in casinos etc. Other uses include spotting dog and cat urine and spray stains. This is done by turning out the lights in the room and turning on the UV light and the things you don’t want there will show up by glowing. What other uses can you think of?
