I replaced both low beam bulbs on my 2007 C280 4MATIC, with Sylvania H7 standard halogen bulbs after one of the original bulbs burnt out. Now when I drive at night, I see two thin bright overlapping parabola shaped light patterns on the road on top of the general beam pattern generated by the new bulbs. With the original bulbs, I used to get a uniform lighting pattern only. The bulb replacement was easy, so I am not sure what I could have done wrong to cause these distracting parabola patterns to arise. That you in advance for any feedback / suggestions.
