How to remove and install headlight housings on Mercedes-Benz C350?

Open the hood and prop it up all the way. If only one headlight housing is being removed, loosen the bumper on that side and cover it with shop towels to prevent scratches. For both headlight housings, remove the bumper cover. Remove the headlight housing bolts, including the upper mounting bolts, lower mounting bolt, and thumbwheel. Pull out the headlight housing and disconnect the electrical connector; if the vehicle has xenon headlights, disconnect the vacuum line from the bottom of the housing. Installation is the reverse of removal. Have the headlight adjustment checked when finished.

How should headlights be aimed to ensure safety and proper visibility on Mercedes-Benz C350?

The headlights should also point appropriately so as not to distract the in-coming train, thus potentially causing a dangerous road crash or distortion in the driver sight. The aim of the headlights should be verified every 12 months, and when a new headlight is fitted, or a front end bodywork is carried out. Adjustment is performed by an automatic aiming system and in case of failure to aim properly, the vehicle should be sent to a dealer service department or other qualified shop to be corrected.
