Well it's illegal to be driving on a road with more than 4 lights on.
+ that looks kinda dumb. lol
And as far as the holes being used to cool the brakes, I don't know - but if you look at it, they would be placed on the inside of the bumper as the outer hole is towards the center of the tire, so the path would have to curve back towards the middle of the car in order to get to the brake. The hole on the inside can lead right to the brake.
