Got some nice bright white leds for my sides, canbus compatible, others have used them in w204 c-classes.
I'm old school so I do what I've always done, switch the lights on and so I can see when the new bulbs works.
Here's what I did.
Undid the inner drivers side cover and pulled out the bulb holder with pliers. Bulb is on at this point. I take it out and try an led. No light. Try the led the other way round, no light. I try the other leds. No light.
So I go to put the original bulb back in but it has blown. I try several other normal wegde bulbs but no light.
I check the bulb holder metal strips and bend them tight. I even connect the metal loop wires on the bulb to the wires going into the holder but no light.
All other lights are fine.
So at this point I am wondering what on earth so I post on the Merc forums:
Is there an inline fuse somewhere? Have I made a mistake changing the bulb with the lights on? Has the car somehow decided not to send power to it?
And yes, it turns out that if the car detects a failed bulb it cuts power to the circuit and will not restore unless the lights are switched off completely and the bulb replaced with a working one.
Stupid clever modern cars bah rubbish.
