Bi-Xenon HID Problem

[MGargano]

I purchased a 6000K bi-xenon HID kit for my 09 LB in May 2009 from xenon-vision.com, who used to be a vendor here. Apparently they're no longer in business, since that website no longer exists.

Anyway, my driver's side headlight & hi-beam has gone out completely and the passenger's side hi-beam no longer works. I have determined that the problem with the driver's side is not the ballast, since that ballast works when I swap it to the passenger's side.

I'm not sure if my problem is as simple as just needing two new bulbs? On xenonvisions.com (slightly different name from xenon-vision.com, so maybe they're the same company?), I see only one type of replacement bulb, but it doesn't say whether they are bi-xenon or single-beam replacement bulbs, so I'm not sure what to do from here. I assume the bulb itself is different between the bi-xenon and single beam kits?

I've emailed xenonvisions.com several times with no response and have tried calling the number listed on the site, which rings twice then hangs up.
