I have recently bought a 2010 Mercedes C250 Sport (W204). Over the last three weeks I have had to replace the nearside front parking bulb, along with the offside front dipped beam bulb. After a couple of days the new dipped beam bulb failed again so I swapped it with another new bulb. It too did not work, so I assume I have a faulty connection somewhere, or there is a fuse blown, assuming the dipped beam bulb has its own fuse?. Can anyone help me please, especially with a fuse description, layout and location.
