I took delivery of a 2004 GTP last week. I've noticed that the headlights are very jiggly when the road is even slightly imperfect. But I can't see that in the light pattern on the roadway, only when I'm following another car. The lights don't bounce so much that it reaches the other car's mirrors, so I don't know if it's dangerous, but I think it would annoy me to be in front of myself, if you can follow that. The dealer doesn't know yet if this is normal since I'm driving their first sale, so I thought I'd check here to see if anyone else has noticed this.
