Hi All,
I drive a 2009 W204 C200K.
For the last 3 years every 6 to 12 months my car's headlight bulbs keep fusing.
I replace the bulbs with top rated bulbs, but then it fuses again.
When the car went in for a service, I asked them to replace the parking bulbs and I asked why this is happening every few months.
I think they said they cannot replace the parking bulbs. MB advised that to resolve the problem I need to replace the entire headlight cluster.
I am still not sure what causes the problem, but I am at the point of purchasing the replacement units.
The original equipment is extremely expensive. So I am opting for a generic unit.
Does anyone have experience with this issue and were you advised to do the same? Did you buy generic or original parts?

I dont know what fusing is. Does that mean they burn out? If they are burning out prematurely it can be improper installation-not wearing gloves/getting your fingers all over the glass, worn sockets, water or moisture-are the dust covers installed?, voltage fluctuation-alternator/wiring issue.
Which bulbs, be specific, more than one bulb at a time?
The parking bulbs, do you mean the two bulbs at the very top of the headlight, the eyebrow lights some call it? They are replaceable but it is a pain. I believe I used a set of needle nose pliers to reach in and remove the bulb/bulb holder. Those bulbs are specific blue looking bulbs and a bit expensive, i just used equivalent regular clear halogen replacements which are the same as the rear side marker bulbs. They give off a slightly brighter more yellow look but I dont care.
The various bulbs are pretty inexpensive, I bought bulk 10 packs of each bulb from an online electrical store. Just make sure to buy the LL/Long Life bulbs. The Osram bulbs are cheap too.
My W204 has regular halogen H7 high/low beam bulbs and I couldnt see at night, i installed an aftermarket HID kit and see much better and ive had no issues the past 4yrs.

I don't know what 'fusing' is either, unless you mean it literally where the connectors for the bulbs are fusing to the bulbs. It could be the car was rebuilt after a collission and the wires are not the wrong size but that is the best guess I can make...as unlikely as it sounds even to me. if they're just burning out, they're overheating for some reason would be my second guess.
