Tried google, philips website ( Philips Lighting Asia Pacific ), bhp posts but still struggling. Can someone educate me ?
well basically the bulbs sizes are the same as normal bulbs sizes. your car would probably have h4. most hids are 35w though you can get 55w. the colour temp is eg 4300k - the most light will be visible from it. as you go on eg 6000k, 8000k, 12000k the visible light becomes less and the colour is more towards blue/purple. so you should ge 4300k for a whitish/yellow light or 6000k for white light/ slight bluish tinge.
