Can someone tell me what a good replacement halogen bulb would be that has a similar color to the zenon low beams?

I realize whatever I put in there won't be as white, and I surely don't want something so BLUE it looks like a ricer boy racer wannabe.

Searched for the thread I thought I saw in this forum but couldn't locate it sorry

I did put in a set of PIAA 4000K bulbs, that helped some and the light isn't scattered all over when they are on, like some I have seen. In fact the bulbs themselves only have a touch of blue which is fine.

Thoughts anyone or photos of your R230 with some fitted?

Thanks in advance,

J T
