Park lamps iluminate with brakes

Actually, I've thought about "front braking lamps" for many years. Let's say you're turning left at an unprotected (no left turn arrow), and you're waiting for cars to pass by. Suddenly, the light turns yellow. IS THAT CAR coming towards you at 45mph going to STOP or BLOW THE YELLOW? Meanwhile, you either take a risk and HOPE the driver stops, so you can complete your turn, or you wait in the middle of the intersection not sure what to do. It can be quite scary to wait in the middle of an intersection during these few seconds. I think front braking lights, illuminated yellow using the parking light, could work. This would assure you (the driver turning left), that the car coming towards you is BRAKING and will allow you to complete your turn safely. I think this should be required on all automobiles, we need some kind of system that has front braking lights for these types of situations. Could also be useful for pedestrians.
