Caution front brake lights work just like the rear brake lights do but they only when your turn signals are on. This lets oncoming traffic see when your going to turn left or right in front of them. This also lets pedestrians know when it is safe to cross the crosswalk letting them know when your going to make your turn. This is my patented idea that I have on my truck and people will step back onto the curb when they see you coming and oncoming drivers stop knowing when your going to make the turn.
This makes your vehicle more safe with it than without it.
