Your City has H4 bulbs, however, installing HID in Halogen Reflector headlight will be pointless and dangerous for oncoming traffic.
Now for the projectors, I doubt you'll find HID Projectors in Pakistan, shopkeepers will sell you Projectors saying they work brilliant with HID, but sadly, they're totally unaware that these are mostly Halogen Projectors which are not meant for HID's.
The best option we have here is to buy HID Projectors from Scrap Yards and do a retrofit in original headlights or another pair of headlights, the results will be worth it, neat look, excellent vision, sharp cutoff, happy oncoming traffic
