hahaha! took the front end apart today (you have to to get to the HID Headlight assembly).
It was the bulb! OMG was it the bulb! I'll post a pic of it tomorrow. Hunting down a d2s bulb is not an easy job either! Long story short...I found the bulb at a Nissan Dealership for $100 + tax (CA tax) = $108 out the door.
I tried many places looking for the d2s bulb. Honda wanted $180, Acura wanted $260, Inline4 wanted $150 and had to order it, but finally, I arrived at Nissan for $100.
Honda and Acura were both out of stock. Nissan had it! Also, the parts guys are idiots, and can't tell the difference between a d2r and d2s.
