The Credit Card Light-bulb is a card-sized gadget that lights up when the flat bulb in the center is folded up.
It’s affordable and small enough to fit into any sized wallet without taking up much room. The bulb might not be as bright as a flashlight but it’s definitely more convenient to hold onto and it will do the job when necessary. Batteries are required and included.
Also available in different card colors.
I think that the Credit Card Light-bulb is a cool toy but I believe that a majority of us now carry devices called “cell phones,” which have flashlights that are probably much brighter than the Credit Card Light Bulb.
