For most of our daily use things, offcourse imported ones, we don't know where they are manufactured and assembled. Today if we try to buy hungry made cell phone, we can have doubt of fake one, but if we buy china one, it will be 110% genuine. This is the way we have to live like. We can find many imported products which are cheaper in Pakistan than many other countries. Have you ever go to road that leads from Holiday Inn towards Cooper road. After going few meters, at right side you can find shop selling shampoo products etc. Can you guess they are genuine, where they are manufactured and assembled. Shah Alami and Gujranwala are famous for their assembling plants 
If you are buying headlamps Philips Rally just for 200-300 rupees, forget where they are manufactured and assembled. Buy them 
As they are 100/90 watts, I suppose they give more light than standard hallogen bulbs of 60/55 watts.
I changed bulbs from Philips Diamond Vision 5000K to Philips XTreme Power both are 60/55 Watts. Both versions distinguish my car with most vehicles on road. I have 80% more visibility with XTreme Power.
