Front Brake Light

I would like to see a brake light on the front of cars and trucks. The reason I say this is because of all the times when people are crossing the street and have no idea if the car or truck that is turning has applied the brakes or not. I'm thinking of a brake light similar to the third brake light in the back of a car/truck maybe located on the front grill.

I saw the need when a road worker was franticly swinging a stop sign to get a car to slow down on a one lane road.  Since then I have noticed hundreds of situations that a front brake light could have be very benificial.  I think it would be the inovation of the century.  Penny York
