I have an '06 S430 4Matic (36,000 miles). I recently had a headlight bulb blow on me. I replaced both bulbs ( H7) with Sylvania SilverStar bulbs. I then noticed that the drivers side light was dimmer than the passenger side. I went back today, and replaced those with standard Sylvania H7 bulbs. When I went to check again, the driver's side is still much dimmer than the other. Please Help... Thanks in Advance.

 

probably aimed incorrectly so it looks dimmer

 

Chassis221, I've tried turning the bulb several times, with no change. Is there anything else that I am not doing correctly, or need to do?

 

Walk a good distance away from the car and bend down low to the road and look at the lights.

If it still looks dim...

Check the electrical connections with a multimeter, DC Volts. See if the voltage is lower on the side which is dim.

A poor electrical connection or damaged wire will not let as much electricity "through" to the light.

I don't have electrical diagrams for that year, but there can be various electrical connections on cables going to the lights, a relay (electrically operated switch), etc.
