No obviously not. I build 400-800 whp street driven cars for a living, so you assume correctly I didn't use a blue bulb. If you look at the pics of my previous cars, you can pretty clearly see that they have HID lights.

The bulbs and ballasts used in those setups are OEM Audi HID bulbs and ballasts that I made an adaptor for on my mill from billet aluminum to mount them into the housing. I measured the length of the stock bulb to the arc point then made an adaptor to bring the OEM bulb into the same spot in the housing. Even with that they still glared like crazy.

But say the general focal length was adjusted, the shape of the arc tube alone will result in problems. Because of this, retro-fitting HIDs "seem" to work better in projector housings since the cut-offs appear similar. But, changing the focal point changes the overall photmetrics - for the worse.
You obviously are not reading what I posted. I'm refering to the aftermarket HID lights from CQLight.ca. The Focal point in those aftermarkets ligth ARE IN FACT moved so they work better in a non hid housing. Standard OEM bulbs you would buy at the dealer are not, that is obvious because they are made for HID housings. Different bulbs like H1 H7 9004 are all NON hid lights. They all have different arc points in the bulb. So when you buy aftermarket HID lights in H1 H7 or 9004 they put the arc point of the hid bulb to be the same as the non hid bulb to help minimize glare. Again this is only for aftermarket kits. Nobody is talking about Philips , GE or Sylvania only aftermarket kits those brands are OE and obviously not the same.

The point of what I was talking about was to say that in a standard non HID lamp the aftermarket HID lights are a bit better and retrofitting lights from another manufacturer such as I did with the Audi setup in my GTI and Talon. I have tried both in both housings. The Audi setup put the arc point was too close to the reflector and way closer than the stock light was, the aftermarket hid lights kept it in the same place. There was still a lot of glare however.

See all the wiring from the ballast and ignitor? It's built into the unit, so its obviously wired to handle it's own power. This is not something that even concerns an aftermarket kit. You only hook up power and ground which is 7.5amps per side and doens't draw much voltage. 18ga wire would handle that.

It's fairly obvious that you have never handled an aftermarket kit. They work, but not like an OEM Litronic upgrade thats for sure. I agree there will be lots of glare and you shouldn't have done it.

I was simply passing on some of my knowledge on using OEM HID's from a manufacturer in a non HID housing (Audi Hid's in stock GTI or Talon Housing) and aftermarket HIDs in a stock and projector housing. I have done it all with HID's every bult type in every housing configuration. Honestly, there is nothing like stock HID's and without the full OEM Litronic kit you will never get light like an OEM car. We both definately agree there.
