I was wondering if anyone was having this similar problem. I replaced both inner and outer eyebrow lights with LEDs w/ resistors but only the inner one stays lit while the outer one flickers or intermittently comes on. I thought it was a bad LED so I switched it, same thing happen and on both sides too. These are the same LEDs my friends have on their '08, '10 C300, difference is they don't have the LED fog DRLs on the '11. I later took the same LEDs that didnt work on the eyebrows and replaced the license plate light with them, that worked.

It might be a connection problem, plug the led in but don't put it back in the housing yet. Turn on your lights and see if it still flickers, if it does, play with the bulb position a bit and see if it helps.

Is it still flickering?

I've got a question - i bought these : a while back to experiment with.

so far i have only removed and replaced one bulb and when i plug in the new LED bulb, it illuminates very low, and stays on when the key is off/removed. In addition to this always-on-low condition, it never turns on brightly once the parking lights are illuminated.

I'm guessing this is an issue coming about from voltage being directed away from the bulb as it thinks the bulb is burnt out, yes? How do you guys get around this?
