Just to show my somewhat envious position - have you thought about using:
Philips Blue Vision
"For the first time here is a blue bulb worthy of our Best Buy award. If you must have the xenon look, the Blue Vision is the best of those tested"
Available in: H1, H3, H4, H7, 9005, 9006 - in stock and ready to ship.
and sell both your headlamps and dead HID lamps to me for some ridiculously low price??
or better still swap my fully working units for yours
BTW - HID lamps are available from
www.powerbulbs.co.uk and are around 100GBP each.
