A long time ago, when I was in high school... or maybe it was just out of high school, a couple buddies of mine came up with a great idea. After a long weekend of camping and opening Pepsi's when they wanted MDG's...they thought about adding a light bulb... much like in the refrigerator... so when you would open the cooler a light would come on and you could see which beer you were grabbing.

They called it the "Coolight". Quite possibly the worst name in marketing but a good idea nonetheless. They never followed through and left it open to these guys who are marketing a cooler called the Coolest.  It's not only got an LED light but Bluetooth speakers a blender a USB charger and a bottle opener. Just more proof that me & my friends are failures.
