This is a JB Tokusho Andon (light box) panel. I'm selling it because I replaced it with a different panel. It was attached to a Unic crane truck, so it's designed for a crane operator. It has a Mutsu-style gradation. Light passes through from the back! It's not from Hakuginsha. Images 4 and 5 are photos taken immediately after installation. There are scratches and dirt! Please note that the Andon light itself is not included.
