Now if you are considering HIDs, I've been messing around with them for a few months, and I have learnt a lot. I hope this is helpful.
They are certainly very bright, though there are lots of downsides. The first of course is that unless you have a car with projector lamps, self levelling suspension, and headlight wipers, HIDs are illegal.
If you must have HIDs.. higher number means bluer it does NOT mean brighter. 4300k or 5000k will get you the best light.
Its not as simple as that either. HID lamps have a different focal length than H4... the light source is in a different physical place within the light. This means that a reflector which is designed to focus the light from a H4 globe in a particular way is not capable of focusing the light from a HID in the same way, because the light source is in a different place.
Looking at your links for HIR, it looks like they will have the same problem.. the light source is not in the same place as the originals. I don't have a VE though, my assumption is they normally use H4/H1 as well? If they do, then HIR are going to have all the same problems as HID.
It throws some light in the wrong direction, which is why HIDs get such a bad rap from other motorists.. its throwing it straight into their eyes. You can compensate for this to some degree by adjusting your lights further to the left and lower than normal. This will stop you from bothering other motorists, but you will lose a lot of the advantage of having them in the first place, because they aren't aimed right!
They are still better than standard lights though, even adjusted like this.
I removed the 8000k 35w HID high/low beam and replaced them with Philips Extreme Vision H4s. I've left the 10000k HIDs in the high beam for now, but when I get a Round Tuit, I will buy 5000k 55w HID for the high beam.
Since I dont need high beam around town, I was able to readjust my lights again, and the Philips globes are great.. and legal..
This is what they look like now.
When I hit the open road, the HIDs now correctly adjusted in the high beam are awesome. They still throw some light in the wrong direction but if I blind a couple kangaroos I am not going to cry. I am careful about dipping my lights early though, I wouldnt like those things pointing at me. Looking forward to getting the 5000k 55w HID , that will be spectacular.
I don't have the option of buying projector lights for my VS.. if you can get them for your VE you are mad not to in my opinion.
