Upgrade Xenon Ballast Unit

[viperbl]

Audi are looking for around 250 quid for the new Ignitor unit for the RS4 headlight unit that I have ... this company I contacted http://www.xenonvalot.com tell me they can do a upgraded unit 35/50w version for 500 Euro's.

Has anyone done this, and what is the wattage of the stock RS4 unit??? anyone know???

Also, does anyone know if the S4/RS4 Ballist/Ignitor Unit is the same part? I have a part number of 8D0 907 391A ?

So sorry cant help but if anyone has etka maybe the would post both numbers, Light up grades may well be a good mod.
Some people have up graded simply the bulbs, would be great to hear which h7 bulb they went for and if they are significantly better.Also.

I bought 55w ballasts and bulbs from SPP in the states. The ballats etc are the same, but different across B5/B6.

I have bought a 50w Race kit from Apexcone in the States. I got this through www.understeer.com for $375 including shipping.
It hasn't arrived yet so I can't comment on it. It's a proper kit though with 50w Ballasts AND Bulbs (I have gone for 5000K). The
SPP kit is $500 which seemed a little high to me (I am a stingy bastard!).
