Flip Dot Display Road Construction Changing Message Sign

They don't have too many of these anymore. I've seen in a few places where they even embed LEDs in the flaps so they can work in darkness too. The big advantage of these is they can even work if the power goes out. (The message just stays at what the last one said)

Hi,
I'm not really a regular uploader yet. I still don't have enough subscribers/watchers to get paid. I'm just uploading clips of things i recorded over the years. Eventually i plan to cover retro computers/electronics in videos as i sell off my collection on ebay (my full time job is selling online)

I used to live to run test mode on these things...

These must be replaced by LED displays today.
