Stock bulbs does not mean Halogen bulb.
For a car that comes with HID's from the factory, its stock bulb will in fact be a HID bulb.
Same goes for a car that came with Halogen bulbs from the factory.
I hope that makes it clear.
second, i just wanted to re assure ; whether or if i get those projector cases. I should Not install Hid in it [ but regular /stock bulbs] with high intensity?. Am i correct?..
Yes you are correct.
If you get aftermarket projector lights, 100% of the time they are made for Halogen bulbs and not HID bulbs.
If you will use HID bulbs in those projectors, than you will probably get worse output than what you already have with your regular headlights.
Generally Your opinion did vary ;
Some [cases] that are meant to be used with Hids are not aftermarket ??
My opinion did not vary my friend.
All aftermarket projectors are made for halogen bulbs.
aftermarket is like a retrofitted
Aftermarket is different from a retrofit.
Aftermarket projectors are essentially ready made projectors that you buy from car accessory shop and are always halogen.
A retrofit is when you [U]take projectors out of a car that came with HID projectors from the factory and you fix those projectors in your car hadlights(which requires cutting of your original headlights).

You showed a couple of videos in which the beam of those Hid projectors created a nice Cut off Line of the light.I noticed In regular stock cases the thing that normally happens the image is usually distorted for the person sitting behind the wheel. And the light is too much for the person standing in front of car ..
HID projectors as well as Halogen projectors produce nice cutoffs.The problem starts to happen when you start using HID bulbs in Halogen projectors.
So ; yet again what is the best thing i could get ....For the car
If you really want projectors than I would suggest buy the aftermarket projectors and only use Halogen bulbs.
If you really want HID's than what I would do is to do a retrofit.
We as drivers share the road with other drivers and have to courteous by not installing HID kits in our regular lights, which literally blinds the oncomming traffic and causes accidents.
It entirely is a personal choice however.
