I just got my civic si from the dealership used as-is warranty and everything seemed to be working fine. However, I noticed (later on) that one of the headlights was off. I tapped it a bit and it turned on. Further investigation lead me to see that the left headlight is LOOSE and can be pushed in and isn't snug with the bumper. Does anyone know the possible cause of this? And the possible cause of the headlight not working unless I bump it?

Maybe the previous owner had aftermarket headlights and sounds like the connections for the headlight bulbs might not be fully connected and they are loose.
