Adam- I like HID's but again, you just lost your high-beams like you acknowledged. However, it's not a question IF the electronics on your HID go bad, but when.
If I were you, I'd change the Euro headlamp lenses to 500E lenses so you can use your fogs as headlamps.
Also, Dean mentioned a site that uses Philip -based components to make a HID H4 replacment like yours, but with a HIGH BEAM as well!
Note- I said Philips-based. Philips does NOT engineer these kits. Distributors merely put together the pieces, and change the sockets to H4, H3, 9005, 9006, etc.
