How do chally fam? one of my headlights is going dim, and im pretty sure this means its time to change it out, but the dealer is talking about $230 for the bulb. i looked in the manual, it says i need HID D1S bulbs. can anyone point me in the direction of a good name brand bulb, plus a good company to purchase them from? i seen some on ebay, and amazon, but kinda skeptical. any in-put will be appreciated! thanx in advance.
