Waiting through 2 green lights for 80 bikers

I was by Home Depot and enjoying watching a club of about 80 bikers drive by while I waited through two green lights. I don’t remember reading this law, rule or maybe just etiquette, and if so, when should we yield? When there are 80, 50 or just 10? And if so, are there some other clubs we should also yield to — the fishermen with 10 boats and trailers or 10 semis?

Can someone please clarify this rule so we don’t try to go on a green light when we are not supposed to.
