no higher K values mean they are close to blue/ purple and the light scatters more than it casts or throws in one direction; means less visibility for the road ahead and lots of angry drivers seeing annoying blue lights when coming from the other direction

I posted a temp chart in another thread ..

ok, but has anyone done this. i don't know how to go about it. does the whole headlight unit need to be taken out or what?

No, remove the "bulb" or capsule just like you would a regular bulb. I believe it twists out. You ned to make sure the conectors are the same.

I dont know what year X you have but I have a 2001 and I've replaced the headlights with 6000k bulbs and retrofitted the fog lights with a 6000k fog light bulb kit.

They came out great but I havent taken pictures yet. On my car, I was installing angel eyes simultaneously so the headlight units were out already but I'd imagine given the small space to work with, yes, you need to take the headlight units out to change the bulbs. I know you definitely need to remove them to change the turn signals. There are star point screws that hold a weathertight shroud over the xenon bulb so no moisture gets in there.

As for necessary tools, there is a diy post on the homepage on how to change your turn signals. You can follow that to get the bulbs out (if you happen to have the same setup as me, of course). The only tool I definitely could NOT have done without when I did my swap was the wobble head extension because its next to impossible to remove the screws from the front bottom of the headlight without one. Even with it, you run the risk of dropping the screws down into the bumper.

Good luck.

PS I got both as a package on ebay from seller fishcake321 for about $200.

The e70 must be different. I had my headlamp assemblies replace under warranty and it took two days and they had to remove the bumper, fan and shroud and a pump amongst other parts.

I believe the OP was talking about replace bulbs not entire headlamp assemblies.

yes, i was talking about replacing the bulbs. this is on an E70, and there doesn't seem to be much room at all to fit your hand in there and successfully take anything apart. so i'm guessing the easiest way would be to remove the entire assembly from the car? anybody know what kind of tools i would need or what else this might entail?

I have a suggestion.. change the Angel eyes and the fogs but leave the rest alone !!!:p:

Could anybody else that's done the HID bulb replacement on an E70 post how they did it?
I just got an e70 and want to change both HID bubl, angel eye and Fog lights.
Thanks!
