2011 C300 Sport Fog Light Question
How do I put the LED Fog Lights on full brightness?
With the switch on A, the LEDs are on but dim.
I hit the Fog light button and the indicator comes on the dash, but the LEDs go out. I hit the Fog light button again, the indicator turns of, the LEDs get really bright, but then go back to dim. Same happens for every position of the light switch.
Basically I cannot find a way to get my the LEDs to go to full brightness.
What am I doing wrong?
(BTW, I've searched but I find a ton of threads about retrofitting and/or changing the color, etc. Nothing to do with what I'm asking. Or at least not on the first couple pages.)

The front LEDs are daytime driving lights. It senses environmemt light. During the day it turns to full brightness, and in the evening it dims. Fog light is in the rear left side lamp assembly only not in rear right side, strange enough to me but is designed that way. When fog light is turned on, front LED dims to minimal and rear left side light becomes brighter than right side. It is for drivers behind to see you, not for you to see drivers in front of you.
Luxury model has two fog light buttons so I believe it has both front and rear fog lights.
