You all know the vehicles have two side light that is Right sidelight and left side light. They two Blink when the diver on the button. when the vehicle is going to turn to right than the driver on the right sidelight so, the right side light blinks when the vehicle and when the Vehicle is going to turn to the left than the driver turn on the left side light so, the left sidelight blinks when the vehicle is going to turn to the left. This is the function of sidelight when the vehicle is going to turn to left or right.
Another function of the right side light is in the Highway that is when the vehicle is giving side to the backward vehicles than the driver turn on the right side light. Than the backward vehicles know that the vehicle is giving side so he over attack the vehicle. This is the function of right side light of vehicle I know.
Anyone can suggest more about the Sidelight of vehicle than you can email me at in srryforthatblame@yahoo.com or simply you can comment me here...
