Hi Guys probably a bit of a trivial question but I want to get better bulbs for headlights but just want to plug them in no wires or boxes to change just a straight swap any suggestion would be gratefully received .
Oh car is an 05 plate A6 Allroad 2.5 tdi Quattro Thanks again.

Have you got Xenons or not at the moment?

I have the same car and have tried all sorts to get better light. I have finally bitten the bullet and have rebuilt two complete units with new bi xenon projectors and new xenon bulbs I am hoping this will fix it.

I think they are just halogen , That doesn't sound good, is there a headlight unit from another Audi that I could replace original with ?

There was a factory Bi-Xenon system option offered, it was much better than the naffy candles, but nothing like modern Xenon (HID) lights.

A pair of C5 halogen lights can cost as little as £50 from a breaker, maybe £80-90 for a good set.
The bi-Xenon C5 sets are more like £150-200 from a breaker.
Allroad lights are fewer and cost more than the basic C5 lights.

I just re-built a set of C5 lights with new Chi-bay projectors and HID kit.

£55 lights from breaker
£5. Silver/chrome paint for inside surfaces
£14 H1 HID kit
£30 LED halo 2.5” projector

They are done, but not in the car yet.

How bad are your lenses? Just by cleaning up mine and fitting Nightbreaker bulbs I am happy enough with how they perform now.
