Lights a bit yellow - bulb options?

Yes this is about right.

Personally I tend to find the 5-6000k bulbs more to my liking as they are more 'pure white'

Reason OEM colour temperature is around 4300K is because that's the peak output lumens/watt. Once you're over 6000k the output brightness reduces.

There are 2 lenses on the bi-xenons the inner one is plastic and clipped on. Goes dull with age, but don't recommend anything more aggressive than water to clean it if you decided to strip the lights. The silver finish on the edges of the inner lens isn't terribly robust to chemicals!

Is it just dipped beam you're not happy with?

Hi,

Informative thread, thanks to previous posters.

Like the original questioner, I need to find out if the lights on mine are bi-zenon and I don't have access to the VAG.

I do have the "spec" sticker for the car; what would I look for.

They look precisely like the picture in the first post of this thread - if you don't have the round flash and side light holes in that position, and the silver trim strip running across under the bulb then it's single xenon.

Bi-xenon are pretty distinctive to look at - if in doubt go from normal beam to high beam with lights pointing at a wall and you should see the flap move in the reflection. If you just get more light and the xenon beam doesn't change, then again it's most likely single xenon

I recently changed my bulbs to the very latest Philips X-tremeVision 'gen2' Xenons:

Not cheap, but nice improvement over the old bulbs.

Thanks Adrian, you're a star, I don't have them: can they be realistically retrofitted? Any idea of cost?

The lights are poor at the moment. I could also do the clean routine but I notice that the lights on my S Reg Fiesta are better right now!

They used to be arse-buckling expensive, even used, but might be worth a call to the sponsors. I'm sure people have retrofitted them in the past without issue - nothing overly special about them in terms of design.

Bulbs are the deciding factor with any headlight, and condition. If yours are milky or reflector is worn then new bulbs won't help as much.

For non-xenon bulbs I've always sworn by Philips Xtreme Vision Plus as they're about £20 a pair from major ebay sellers - I used them in the main beam support/flash in my bi-xenons and for front fogs. They burn brighter so the downside is a shorter lifespan if used as your main bulb - in our A6 you'd get a failure after 2 years.

I think that legally speaking you'll need self levelling and headlight washers to have xenon lights, although it seems no-one will be checking!
