I just bought "yellowish" philips weathervision bulbs (9005 - high beam with BMW headlites conversion). And actually they are great! Not many times u use high beams on the road but in bad weather conditions shouldn't u wish u had 'em as fog lites? Just wanted to share.

Anyway ... I came across a nice article on lumens and halogens (I saw a plenty of posts with a question which to buy). So here it is:

Those HB3's (9005), put down some serious lumens according to that website.
