I'd be interested in changing that as well, perhaps with alfaobd?
Loved the HIDs performance, but just couldn't get the reliability out of them (and it's never a convenient situation when one of your lights goes out randomly, or at least it never was for me). Mine worked flawlessly til the day they didn't, never had any issues with water or the bulbs, always the balasts. If I lived in a different part of the country I would try running them again, but up here it just seems like asking for trouble in my experience (my last set was my 5th, ranging from cheap to not cheap). Since the LEDs have caught up enough to the HIDs, I had to give them a shot this time and really think they have a good chance of not giving me issues. Time will tell though, these may just have some other problem I'm not even aware of yet.
I also didn't mind the warm up time, but good call on the LEDs for high beams for the instant light. I still have HIDs in my 66 buick since that doesn't get exposed to the elements like my trucks do. I'm curious to see how the LEDs would do in those housings though, I might do it and see if it cuts down on the glare. I need to run something in that car though other than the stock "candles" is what I would describe them as in terms of their effectiveness.
