And as just a citizen like most of us, I really hate that cheapest model. Usually ends up the most expensive as they have to fix the garbage they install. I really don't give two flying fucks that they go the cheapest option, I'd rather tax dollars be spent on the right solution to begin with. The cheapest option is usually also the most corrupt option, giving the tenders to mates and family. And yea, we nationalised to led signals almost 2 decades ago, but then again we don't have to worry about snow here for the most part. The best thing about led is you can still see them when you have the sun in your face, or the sun is shining right on them. They could install some small computers running block chains to heat them up.
