Bro it is suggested worldwide .. Here I am attaching chart for further clarification :-
HID bulbs are meant to be used in HID projectors .... Though Our illiterate people and electricians recommend us to use them in stock crystal housing which gives damn good light but actully it is the worst light for oncoming traffic ,and also no proper visibility and focus point of light ....
However due to scarce means of branded goodies we have to live with what available locally ,Projectors are not available however one can import one if he has links ....
Solution is if you want visibility without the hassle of hid and projector retrofit ... Than you can focus on halogen bulbs ,A simple bulb is called as halogen however for bikes we need H4 halogen as H4 is socket .... Same as the case with the hid !
Branded bulbs like Osram nightbreakers,Narva,Phillips PIAA,Denso are a good replacement than stock ... Also PIAA is a bit expensive but works wonder ....
It will cost around 8K pair including shipping charges ,Though you can sell the other one to save your cost ..... But you ahve to import them!
Though if you get projector with hidz ... there is nothing better than this !
I hope it clear the situation !
