Thanks TB5 for the great pics. I took on the eyebrow replacement with AZNoptics LEDs and have a few observations from a rank beginner. First, removing the trim pieces held by those plastic fasteners only requires pulling up the plastic center post with your fingernails or a thin screwdriver blade. I pried the first two thinking they were all one piece and broke part of the plastic screw. Short and long needle nose pliers are needed to grab the sockets. If you leave the eyebrow lights on while doing all this it's possible that the lights will go out and you have reboot the system by locking the car and starting all over again. Not sure what the exact sequence is, but to my surprise the lights do come on. Another thing. The LEDs are very delicate. The top of one broke off as I was trying to insert it in the socket holder. So I have 3 LEDs now and one normal one. The LED must maneuvered so that it fits through the cilindrical holder. Can't just push it in there and hope for the best. That's why it's useful to have them on. Lastly, I found it impossible to fit the drivers side led without loosening the windshield wiper reservoir. Thanks to all in this thread.

 

I came across a video on someone showing the procedure on how to replace the LED eyebrow bulbs on a W204 C350. Hope this helps.

 

Thanks. I like his suggestion to keep an assortment of light bulbs for the vehicle on hand.

 

TB5 thank you for well documented DIY. I changed mine a couple of weeks ago. This DIY was very helpful and useful. Well done!

Maybe someone in here can help..I just ordered some W5W Canbus LED's for my eyelids on my C350. The seller personally has a C series and has used them in his with no issues (even has pics on his ad).

My LED's flicker and either stay on when the lights are off, or will flicker off and on even when power is cut. They won't stay on constant even when driving around town. I've tried these LED's on the interior, license plate and trunk, and they work fine everywhere but on parking lights.

Any ideas? I don't believe it to be the bulbs.

 

Sorry to bring an old thread back, but i installed some LEDs and now they flicker.
I got the leds from v-leds.com.

 

Bad LEDs. Use AznOptics. Vendor on here, great products and customer service.

Hello guys,

Did you try flipping the led bulb around?

 

Well I did everything the diy stated, however I might pulled too hard on one of my lightbulb that part of the wiring is out of the connector and on the other side the led isn't working regardless of turning it... **sigh** last resort is take it to the dealer ship and have it all replaced smh

 

It should be an easy fix at a stereo shop. If the LEDs aren't working after turning off the ignition, reinserting the key, then the LEDs are probably no good. I'd go back to the spade 5w bulbs and forget the LEDs

 

pics don't load! please fix!

 

I just completed this job on my car. The yellow plastic bulb housings were very tightly lodged. For what's it worth, I suggest using flat(broad) nose needle nose pliers. I could not get enough purchase with pointed needle nose and they slipped off. Also, it helps to wiggle the yellow bulb carrier before trying to pull out. The outside driver's side was a royal PITA. But patience and wiggling led to success. I was careful not to pull on the wires. I know some say to pull on the wires, but they are fine wires and I didn't want to chance pulling one out.

 

pics update plz?

 

There's no pictures in the 1st post.........
