Thanks all.
PekX2to - I've got the normal bulbs. They look whiter in the photos because of the processing. I was looking to replace them with white ones but some of the reviews I've come across for those bulbs mention that they don't last long and doesn't really have a great lighting distance.
I also need to make sure it won't contravene any Australian car design rules too.
I think matching white foglamps would make it look all the more extra nice tho!
