sorry but sooterbomb is right, it has to do with leagal issues and do note that in the 2 cars pictured above the brake lights are NOT in the bumper, and neither are the indicators (clearly in the tail light lenses),.. seems you have some faulty info on google.
but feel free to believe what you want. i just don't get why you asked a question for which you already knew the answer for....
