I used to know a guy with a lamp on the top of his helmet on a horizontal swivel. It rotated freely so the light would stay level no matter how he tilted his head. But it didn't rotate left or right, so it always pointed in the same direction as the helmet on that axis. It was a rear-facing red light - I don't remember if it also had a front-facing light. I had a conversation with him while he was wearing that helmet, and I couldn't take a single thing he said seriously with that light swiveling constantly.
Recently I met someone with turn signal lights on their helmet, controlled by a wireless transmitter mounted on a handlebar. It's not exactly what you're asking about since I don't think it had an always-on light for visibility. But I mention it because I thought it was pretty cool.
