Over several days ago I have changed the low beam headlights with the 4,750k HID light (not the real HID light kit). Do I need the dealer to adjust the light? It seems to me after installing it, the left light just not height adjusted as on the right.

With the rear licence plate light, I have replaced it as well. But my bro in law recommended me not to put the fading white licence plate light (probably only 60-70% more fade compared to std), in case the jealous police will pull me over and fine me for that. Need some advice in this.

Also, is it better for me to put FM modulator to play MP3 from my mobile phone? Anymore suggestions for this?
