Quoted from NeilMcRae:You couldn’t patent that. At least there are so many prior works it wouldn’t be worth the paper it’s printed on.
I don't recall anyone selling a similar system even without GI or flasher integration before PS started or really even since, do you? I don't know if it's really something that could be patented or not but I do wonder how many here saying it can't be have ever even installed or seen the product in person, clearly some haven't.
