Now, an HID capsule has no filiment, it has a bubble with halides and salts in it. This bubble is about 8 times the volume/reality of the filiment it is replacing. If the light is designed for halogen, and you used an HID capsule in its place, you are completely ruining the optics of the light. It might appear brigher looking at it, and might appear brighter against your garage door, but 200 ft down the road you have about half the output of your halogen bulb.
So what you are saying is that you cant see as good with HIDs in headlights designed with halogen bulbs as you can with the halogen bulbs? If so, its completely false. I dont have one of those "blue" HID kits, mine are I believe 5000k so the light is almost white. I had the same HID in my car for almost 3 years until I hit this gigantic puddle the wrong way and somehow water got into the ballast...and well you can guess what happened. I had to put halogen bulbs in for about a week till I could afford a new kit. Driving the exact same roads at night as I did with the HID kit I felt like I was blind. Couldn't see near as well as I could with the HIDs whether it was raining or clear skies. I see that you are in this line of work and all...but have you ever owned an HID kit or driven a car that had a decent temp bulb? Hell I have even had the same year civic sitting side by side with mine at night on a completely dark street and the other cars lights may as well have been off.
