Which bulb is the DRL on the facelift X5's? (please put your car info in your signature too it makes it easier for us) Most of us have the DRL coded off, unless are you talking about the angel eye bulbs? I would not run any "whiter" bulb that is a DRL, since they are on all the time at reduced voltage its bad for any bulb, I would just code the DRL off (I'm guessing its the inner high beam that is DRL?)
The angel eyes are H8 bulbs, and you can get LED versions off ebay for about 50 bucks, the optics of the rings don't allow for additional brightness, but you can get a whiter look. For your fogs, you have reflector fogs so I would go with the H11 Hoen Xenonmatch bulbs, I used them for years on my Volkswagens and never blew out a bulb (I wipe them down with alcohol prior to install)

trust me, you WILL see a difference from the fresh Philips bulbs, let me know how you like them!
