is there a difference from just changing the bulbs and changing the headlights. cuz I dont want to spend a fortune on the headlights.

The cost is around $700. Go look at this current thread on the A6 forum for more/developing info

You know I wanted those cool blue lights too
until read up on them.
the lights that you see on the new Audis are Xeneon High Intensity Discharge (HID) and there is a huge difference between these and colored Halogen bulbs with Xenon gas in them.

Xenon HID uses a ballast to provide an initial voltage to excite the gases similar to Flourescent
lighting. It must also be focused by a lens so the light does not scatter.
The System is thus two parts, The Xenon HID bulb which is highly pressurized (Pronounced expensive)
and the electronics to start the light then keep it running.

These systems run from 700 - 1200 depending on the brand. The cheaper systems do not include a focusing lens which is important.

Don't be fooled by bulbs that claim to have xenon gas in them. The best you can get with halogens is a white (during the day it still looks yellow) to slightly blue color without the intensity.

I use Sylvania Cool Blue halogens which are White and match the Fog lights in intensity. I've heard that the PIAA bulbs are pretty good but I've never tried 'em.

Search on the web for Xenon HID
good luck

620 for the pair, 310 each. All you do is hook up the + and - of the balast to the stock wiring. Install time takes about an hour and a half. Results are amazing, we installed them in my buddies A4 last night. It's worth every penny!<ul><li><a href="http://www.xenonshop.com/automotive.html">http://www.xenonshop.com/automotive.html</a</li></ul>

they are those cheap blue bulbs that the rest of us rant at. Also with the extra wattage it might burn your harness out, not to mention there are a lot of places that they are not legal.

Do all of those bulbs actually hurt your wiring? What if you rewire it with a larger wire? Cause I mean they look ok and I would only spend about $20 versus $1000...

I ran a set of higher wattage bulbs in my 86 Coupe GT. They were something like 70/80 9004 bulbs. They were definetly brighter, but melted my stock connectors where the bulb plugs in, and melted the reflector inside the lamp! I upgraded to a set of "Euro" lights and better wiring harness, and ran another set of high wattage bulbs. This time they were 80/100. The Euro lights were definetly "superior" to US lights, and were able to handle the bulbs higher wattages without any problems. As was the harness.

The "newer" Audi's, 88 & up, with the newer light designs could probably run the higher wattage bulbs with no problems. However I'd recommend the upgraded harness. The higher wattage bulbs are definetly brighter, but often the glass lamp
difusses the light too much. This is why the Euro's are superior! With the higher wattage bulbs, its like driving around with your brights on all the time!
Of course this varies from model to model.

I found a good set of auxiliary "driving" lights makes up for most headlight shortfalls.

However, on coming drivers did not care much for my brighter lights!
