What do I need to convert my "yellow" headlights to a nice bright white?

Looking pretty. If you want white halos you can fit some LED bulbs. Plenty of threads/recommendations in the archives.

If you want white everything and to be able to see where you are going then the best option is to find a xenon conversion. Usually this means a new pair of lights and a bit of wiring.

And you'd need the same on the left of course.

The nightbreakers would give you a slightly "whiter" appearance but as Rice Crispy says the actual improvement in visibility is nothing exceptional. The effectiveness is determined to a large extent by lumen count. A Halogen bulb is about 1500 lumens, HIDs will get you to about 3500 and an LED will get you 4500-5000. You also need to consider colour temperature. These are the "K" ratings. You do not need anything over 6000K, ever. You'll just end up wasting energy. 4500K will give a slightly yellowish tint to the light. 6000K is white and above that it shifts towards the blue end of the spectrum. You also need to consider what wavelengths your eye functions with most efficiently. This is around the 4000-5000K range. Last but not least its no good pouring out a ton of light if it doesn't go anywhere useful so the focus is important.

The reflector surfaces inside the light housing are designed to operate with a very specific point source. This means that if you have halogen based filament bulbs and you change for anything else you may find the reflectors no longer work with whatever you've put in.
This is especially true of LEDs. There are thousands of designs on the market but most don't emulate the kind of point source that a filament creates.

Your best option is a full xenon conversion but this will mean new light housings, bulbs, ballasts and some cabling and possibly some controller changes. Its generally not cheap to do properly.

If you can find a good LED you will probably need to have the cold checks turned off at the controller otherwise the lights flash when they are off.

Eat carrots and next time remember to buy one with decent lights to start with, cheaper this way....

Depends.... might be lots of carrots though :)

Sounds like you have halogens, in which case Osram Nightbreakers probably easiest way to better dip and main.

The round circular lights on some models are commonly called angel eyes, sometimes they can be quite yellow, there's lots of entries on here how to upgrade to LEDs - that's just for those angel eyes, it is though a fairly easy and common upgrade.

BMW being the nice folk they are, have lower spec cars with daytime running lights that are not angel eyes... just sort of sidelights, while it IS possible, changing to angel eyes could be expensive.

Snowblind did a cover of what he did to upgrade dips to LEDs and the results looked good, but ended up with a bit of custom bulb mounting to get that source of light in the right place, it does matter as it defines the light throw.

realoem.com and last 7 of your VIN might help.
