As for the Hella 4000's HID or not, I have two pairs, halegon, one driving and one pencil, and all I can say is wow!!! They throw out the light and keep the beam pattern, and at only 250.00 or so for the pair they are well worth it. As for the HID's, I have seen them mounted onto an H1 out in Death Valley, and they are well worth the money if you have it to spend on just lights.
