How to replace low beam headlight bulb on Mercedes-Benz W204 C300 C350 C63

You will need a replacement light bulb to change the low beam light bulb on your Mercedes-Benz C-Class W204 model years 2008-2015. Owners of Mercedes-Benz C300, C350, and C63 will find this guide helpful. This only applies to models with halogen bulbs and not to those with HID D2S headlights.

You will need the following parts:

• H7 55W Light Bulb

It is recommended that you replace both bulbs at the same time. That way, the light color from both lights matches, and you don’t have to replace the other bulbs a few months later.

Step 1 – Open the hood

Step 2 – Remove the plastic cap from the back of the headlight.  Twist it counterclockwise to remove it.

Step 3 – Twist and remove the old light bulb.

Step 4 – Disconnect the electrical connector from the old bulb. 

Step 5 – Install the new light bulb. Avoid touching the glass part of the light bulb with your fingers.
