I'm pretty sure there's an thread on that on Audizine

 

My car has the H7 bulb and I can't find a bi-xenon H7 kit.. Am I gonna lose my highbeam or do I have another option?

 

I think you have a 4 bulb system, like my car. D2R (HID) bulbs for low beams and H7 for high beams. Check your manual or on-line. I think Sylvania had a detailed listing on their website for most cars. If so, that's the same lighting arrangement I have. You won't lose any functionality other than slower warm up time on HIDs than Halogens. Flashing quickly and frequently will wear them out prematurely. Have mine for 2 months now and no problems.

Go to HID Online and they should have all the HID kits you need at fair prices. Fast delivery too. I've recently replace all 3 systems with HID kits. OEM D2R or D2C system was actually okay; just needed new bulbs. Dealer wanted $275 + installed for the 2 bulbs. I bought those bulbs for $70 all in (tax, delivery) and paid about 30 minutes labour at Pfaff Tuning for install. My cost, less than 40% of dealer. HID conversion kits require a bit more finesse and wiring, so if you're very good at it, go ahead. I just had Pfaff Tuning install those.

 

Ok last question I promise. I don't want any CPU errors and dash lights coming on so do I need the HID canceller capacitor to fix warning decoder error/flickering problems?

 

whoa there. I have no idea what you're talking about now. The lighting system on the older cars aren't very smart. The CPU won't know what kind of bulbs you've got going. The HID ballasts should also be "invisible" to CPU etc. The burnt out bulb warning system should still work though. I didn't make any modifications at all. My car came with OEM HID low beams, H7 high beams and H3 fogs. I put in new fogs with 55W H3 8000K HID, complete with HID conversion kit and also changed H7 high beams to 55W 6000K H7 HID with conversion kit. I don't have any flickering problems and can't offer any comments on an "HID canceller capacitor". Sorry about that. Is this upgrade for your 2000 A4?
