Claims (9)

1. A method for providing door lock status information via an intelligent lighting system that provides continuous lighting from a door handle, the method comprising:

transmitting a first light signal having a first color from a door handle when a key fob comes within a predetermined area and is detected by a smart antenna in the door handle;

transmitting a second light signal having a second color from the door handle and causing all doors of the vehicle to unlock when a smart sensor on the door handle is activated; and

transmitting a third light signal having a third color from the door handle and causing all of the doors to lock if the vehicle is not entered after a predetermined period of time,

wherein the first light signal, the second light signal, and the third light signal are each transmitted from a light source of the door handle along a first direction that extends from the light source and along a second direction which extends from the light source in a second direction which is opposite to the first direction.

2. The method of claim 1 , further comprising:

transmitting the first light signal when the vehicle is exited, and
