the bulbs probably aren't seated properly in their enclosures. they're keyed to fit one way; try spinning them around until they fit snugly in placeDiehonda said:I replaced my bulbs, adjusted the lights, and now I have a dark spot in the center of the iluminated area(where the silver center cap covers the bulb) so when I drive I can only see what is on the edges of the light, the center of the road is dark. Did I do something wrong or what?
