I just wanted to clarify something about HID lighting. They produce a white light that contains more of the spectrum than standard incandescent lighting. They also produce much more light at 55watts than an incandescent bulb and are cooler running than incandescent (which rely on the heating of a filament to produce light). You can think of HID lighting like flourescent lighting. There are two electrical posts that are suspended within an inert gas. A ballast is used to up the amps and lower the volts so that an arc can jump from one post to the other (just like in a flourescent bulb), between the two posts, the electricity excites the gas and causes it to produce light. Unlike a flourescent bulb, there is no coating on the bulb´s wall to soften or modify the light. A side effect of this is a blue/purple light that is refracted off the sides of the bulbs making them appear blue/purple from the sides. HID light does not shine blue/purple light on the road.The HID stands for High Intensity Disharge lighting. It produses like a purpleish blue lighting effect. They are really bright. The beemers heve em on. There is an HID kit for the scort on NOPi.com i think. A bit expensive.
