Youtube is filled with people into this and many other things we may have no interest in. There are people into security lights, building alarms, vacuum cleaners, trains, air conditioners and many more things. They will have 100s of videos with nothing but. Not saying theskooterguy is an aspie, but many people heavily into stuff like this are. I have some interest people care nothing about, but none of them are an obsession.
Anyway I don't care for LED traffic lights. They had some kind of lights in the 80s that were really hard to see until you got up close. I think they used a mirror inside like a projector. Thank God they don't use those anymore because I found them unsafe. Most around here still use incandescent bulbs. I wish they would time them for night and daytime traffic rather than for just daytime traffic. Better yet use weight sensors on side roads. It is so annoying to wait at a light at night for 5 minutes when no one is coming.
