I installed HIDs one yaer ago. They are exelent.
I got conversion kit for $250 installed. Make sure you buy Dual Beam Design (H13 bulbs). In the past if you wanted to convert to High Intensity Discharge technology you had to sacrifice your high beams. But not anymore! This HID Kit utilizes electromagnetic servo technology that is integrated right into the bulb holder to re-aim the headlight bulb up or down to switch between high and low beams.
