Mercedes benz c300w light bulbs are constantly blowing out. Primarily due to the heat accumulation in the headlights. The plastic parts are melting, dry and very brittle which causes bulbs to overheat and blow out. Left & right parking lights(4), side lamps(2) and license plate lamp(2) have been changed out at least 15 times per lamp. The dealership suggest I change out the head lamp casing costins approx. $2k with labor. Aftermarket $700 plus labor. The service department at three seperate shops have stated this is a common problem with the mb c300.

What owners say
Tl* the contact owns a 2010 mercedes-benz c300. While driving various speeds, the headlights and interior lighting failed. Upon exiting the vehicle, the interior lighting remained illuminated and drained the battery. The vehicle was taken to the dealer where it was diagnosed that the fuse box failed and needed to be replaced. The vehicle was repaired, but the failure recurred. The manufacturer was not made aware of the failure. The failure mileage was unknown.
Front right parking lamp melted into headlight fixture. Was told my mb dealer yesterday it was due to the headlight overheating and I need to pay to replace entire headlight $900.00 they had similar issues with tail lights and had a recall on cars to replace. Maybe something is wrong with front light also.,.
A little less than a year ago my driver side inner parking light bulb failed, and about a week later the passenger side inner parking light bulb failed as well. When I went to replace them, the bulb and headlight assembly showed visible damage from where it appeared as if both bulbs caught on fire and melted into the headlight assembly, permanently damaging both driver and passenger headlight assemblies. There was the presence of charring on the bulb socket as well. I took the vehicle to the local mercedes benz dealership and they stated there was nothing they could do except to replace both headlight assemblies. If it were merely one bulb that failed in this manner, I would have chalked it up to maybe a faulty bulb or socket, but it is very odd that it occurred on both inner parking light assembly. Fortunately
Tl* the contact owns a 2010 mercedes benz c300. While the vehicle was parked, the passenger side low beam head lamp continued to illuminate even though the vehicle was turned off. As a result, the battery drained. The vehicle was taken to a dealer who repaired the vehicle under the federal safety agency campaign number: 14v177000 (exterior lighting); however, the failure recurred on numerous occasions. The manufacturer was not notified of the failure. The failure mileage was unknown.
Approximately once every 2 months while parked with the engine off, the front passenger side headlight will come on with the rear passenger side parking/brake light. When this occurs, I have to turn the headlight switch on then back off, to turn off the lights. On one occasion, I observed the passenger side headlight and the rear passenger light flickering like a strobe light, before I turned the switch on then off.
My car will be parked and engine not running and at any given time the upper front headlight on passenger side and the bottom part of the rear taillight on passenger side will illuminate for no reason. It doesn't matter which position the lights are in. *tr... Updated 04-05-13
All of my exterior light bulbs have been replaced every other month. The rear driver side brake light burned out the metal part where mercedes had to replace the unit. As of monday, april 2, 2012 I had to take my car in the dealer to repair a right front passenger side headlight out. *tr ...updated 03/27/13 *bf updated 04/03/2013
