lol what's wrong with being able to see better at night?
EXACTLY.
I hate this discussion becuase so many people think that even buying an HID kit(boy I hate those too lol I hate a lot of things) is a useless investment. But me having invested over a grand in my retrofit may sound biased but what can I say I hate halogen.
I'll start out here. How can you not like HID kits/retrofits? They give you a better view of the road in
all weather conditions. Who doesn't want to be able to see better in the rain storm? How bout fog? I use to have fog lights, but once I got a retrofit, I could see easily in deep dense fog. Also, when in the fog, other motorists will be able to see you better to help avoid an accident. With halogen lights, I could barely see in the fog or rain with my foglights even on
HID vs Halogen
HID projectors put out such a wide beam of light that allows you to see everything on the side of the road. Also makes it alot easier to spot things on the ground that could be harmful to your car (deer, pedestrians, bikes, mudslides

). And take that against halogen, it has such a narrow area on the road that it illuminates. I personally find it a disadvantage to have halogen in a non projector form. I feel very unsafe at night when I'm in a car that has them. I dont know why just dont ask.
What can I say? It looks like a $50,000 sports car in the rearview mirrors or other motorists and will make heads turn

HIDs bring out a lot of attention on the road so I guess that's always a plus

(unless its by the pigs on the road aka coppers

)
On the downside of having HIDs in a halogen housing can cause a lot of glare and can actually blind on comming traffic lol So it's always a good idea to aim them down to the point where they are still affective. Blinding other motorists is near impossible with the projector + HID becuase of the cutoff will control where the light goes.
Yeah its a business, but its also a growing thing in tuners and domestics. I figure that you can benefit in all forms of HID bulbs whether it is in projector or halogen form. And thats why there is so much hype over it.
HIDs > Halogens
