^^^ now that's a good question. Actually the car has four HIDs (Two in Fog lamps and two in headlight). The Headlight HIDs are installed with stock chrome housing which just disperse the light and make it miserable for front coming car. I want to end the misery of other people so that they shouldn't be blind by my HIDs & secondly due to stock chrome housing the HID projection is not good enough, it just scatter the light here and there.
Now I have two options, either to install proper HID Retrofit (HID housing) or keep the current chrome housing and change the bulb. I'm thinking to change the bulb and keep HIDs in Fog Lamps.
PS: I didn't installed these HIDs 
Those were installed by previous owner.
