I met a guy about 18 years ago that got a patent on a motorcycle light trip module.
He said that he had many hours of fighting with the patent and legal system on this. They said that it could be used to switch lights from red to green, but he said no, it only electronically lets the light know that there is something in the intersection that needs the light for them.

He worked at Tank's Inc and I believe was one of the partners of the company.
It was a 12v module that you bolted to the bottom of your bike that worked to let the light know you were there. I've never seen anything advertised about it since I saw the module in his hand all those years ago.
At the time I didn't think it had a market, but in today's bike age, I think he could sell a pile of them.
