Novaled and Willing are showing a new OLED emergency light. The size is 3cm by 10cm, and it's only a few millimeters thick. They say that while it reaches all the standard and regulations that are required, it's still too expensive to be sold commercially.

It's exactly one year since Kenwood has unveiled similar OLED emergency lights that also double as speakers.
