Okay if your talking about cost effective than here are my recommendations.
The most easily available in Pakistan would be the Phillips Rally bulb which runs at a higher wattage than stock bulbs in cars.That would get you the best results while keeping your pocket all filled up. 
Now, if you are willing to spend the equivalent of HID money and want better results, than go for the Phillips X-Treme Bulbs, you will have to import them as they are not available in Pakistan.Phillips X-Tremes are by far the best Halogen bulbs without question.
An alternate to the X-Tremes would be the Osram Night Breakers, which you would also have to import.
So I'll conclude and suggest that go for the Phillips Rally bulbs and also install fog lights with yellow bulbs.
(Never ever buy the cheap blue bulbs that you can get for Rs.300-500, stock bulbs are far better than them and they are just a mere gimmick)
