The LED lights are called "puddle lights." Commonly found in Bippu styled cars in Japan. Usually, they are programmed to turn on once the doors are open, maybe they flicked em for the picture.
Imagine you got a chick in the car, and you go out for a night on the town, but you didnt notice the gutter on the side of the road had water in it, and she stepped into the darkness......it would suck if you had to hear her the whole night complaining about her Jimmy Choo's...definitley sucked for me.
