Ok, this is a strange bug I presume was created when Codies try to improve the night races but there is a side effect, any light source is on now on any track permanently during the day.  In 2018 some of the tracks like Monaco have the same issue in day time since was tweaked for night races and the lights are on permanently, but it's less noticeable because they are far weaker and don't have the new glow during nights like in 2019.
