does anyone know what these lights are for or when they turn on/off?

i didn't even know there were lights underneath the side mirrors until one day at night, i saw them on while i was walking away from my car. another time, i had locked my doors, took something out of the trunk then came back to the drivers door and i see the light fade in. i tried to recreate it: opened the drivers door. closed it. locked it. walked away, came back, and it never went on. so i'm not sure what activates/deactivates those lights. anyone know exactly?

 

puddle lamps... if u walk pass your car and you have the key in your pocket... it turns on...

 

thanks... but it doesn't turn on all the time even if i have the remote on me and i pass the car. oh well...

 

I think the car doors locked then if you pass the car then it turn on

 

If your far away, just press the unlock button and your puddle lamps and interior lights will light up.
