I have a 2004 Nissan Maxima with the HID D2S bulbs. I think one of my headlight bulbs is going out, as it seems dimmer on the passenger side than the bulb on the drivers side. I have tried to adjust it, however I am not sure which way to turn the adjustment screw to make the light go up or down? Also, how the heck do you replace the bulb on the passenger side? Seems the radiator over flow bottle is in the way. Does anyone have any suggestions? And where can I get a better buy on the bulb, as Nissan wants $125.00 for each bulb.

Second question. Air intake. Has anyone changed their air intake with anything other than the stock one? Thanks. Hope to hear from someone soon. Mick
