Wow.. don't listen to anyone in this thread.. even anderbra!!! (You have 4100k fool!)
The brightest you can get is 4100-4300k. Very bright white, and this is the stock range for factory setups.
About ballasts being negatively trigered blah blah blah... don't buy poopty balasts and this isn't a problem. They should be ground independantly of the balast case :rolleyes:
If you just put the bulb into your existing headlight you don't really need highbeams since you are throwing up so much glare anyways.. lol. I highly recoommend a projector retrofit. Having hi and low beams would be nice, but no matter what your HID low beams will be better than your halogen highbeams anyways. Just get silverstars for the highbeams, or at the very most a cheap HID kit.
If your car uses the highbeams as DRLs (older aleros) then don't put any in your highbeams unless you disable your DRLs. If your car uses your lowbeams for DRLs (newer aleros) you need to disable them no matter what.
All HID kits are not equal, don't cheap out with the mr. Jung crap. Get a kit that has either Phillips or Hella components, or a mixture of both. As for Silvania, they are newer at this, so do some research if you go that route, but they are obviously another good name in lighting. Phillips and Hella have been doing it right for years though.
Any more questions, feel free to ask away
