I am really interested to see how you like the HIDs for your high beams. That topic of conversation has been discussed ad nauseum in numerous car forums, and the general consensus is that using HIDs for your high beams is frowned upon generally. HIDs work differently than halogen bulbs, in that with HIDs, switching them on and off quickly cuts down on the life of the bulb exponentially more than with halogen bulbs and, further, HID bulbs take longer to brighten/warm up. Since with your low beams they are either on or off, HIDs are practical. However, with high beams, you are constantly flicking them on and off when using them more often than not, and that act of switching them on and off will cut down on the life of the bulbs, and further, you aren't getting the full brightness of the bulbs unless you are driving down an empty road with your high beams on for an extended period of time. That said, with HID kits now costing only $35 on eBay, you might ask, "Who really cares? I'll just buy another set."

Just my 2 cents on the subject.
