Schlitz light up beer sign/clock

This sign measures roughly 53x18 inches. I bought it a couple of years ago and I love having it around. If anyone has any information about how many were produced, that would be great. It is in pretty good condition. The sign is made of plastic and there is one small chip in the upper left hard side but it is not visible when hung up. I have tried to find a sign like this on the internet but have been unsuccessful so far. Has anyone else seen one like this?
