LED lights
The illuminated light in Porsche9's pic is aimed to shine a dim light on the ignition switch so you can see how to put the key in it, even in total darkness. There is a either a second LED or perhaps back glow from that same LED illuminates behind the inside door handle so you can see it in the dark, also.
Most of us know where these are, so think of it as protecting your interior finish from the valet's fumbling hand full of keys in the dark.
