Ajm0623, YES! That’s exactly how they are supposed to work! And they work when standing at an intersection. Today, I went to my stealership and showed the service manager, who kept telling me all the lights are working, and asked him to grab the keys as I took him with me to one of the S450’s on the lot. We cranked the car up, turned the wheel left and right then used the signals (we had to cover the light sensor with a black towel). The cornering lights (which are tucked into the inside of the housing right behind the daytime running lights) lit up! The service guys ran a computer program in an attempt to reprogram the cornering lights; didn’t work. Now they had to write in to Germany for a program to have the cornering lights “follow the command” of what the car is asking them to do . . . . Light up at night, when standing at intersections or turning corners or backing up. To all in the thread who thought that this only occurs while the car is moving, I’m not sure you know exactly what cornering lights are. . . . Or if yours even work; these are very distinct lights, you’d know if you have them . . . You’d miss them if you no longer had them.
