Need to buy new head-light bulbs.
I was looking at a new set of head-light bulbs and wanted white ones. There seem to be 2 different kinds. One is the HID kit which costs about $130 versus individual pairs of 'white halogens' for low-beam and high-beam at $25 each, costing a total of about $50. So my question is, what is the difference between them other than obviously the price and how do they work in foggy conditions?
