Yes, HID is a whole lot more efficient and brighter, and with the correct colour temperature, it is a good thing to have. The problem lies in the focussing of the aftermarket HID lamps. On stock low beams (including factory fitted stock HID), if you face a wall, for a right hand drive car, you will find that the focussing pattern to be very clear and sharp, like this: \___\___ As the Xenon bulb is longer and shaped differently from halogen bulbs, simply putting in the Xenon bulb without adjusting the distance of the bulb inside the lamp will result in major loss of focus, the light will flare just like high beams, try driving facing a wall and you will notice the distinct pattern low beam is blurred or even missing altogether. In Singapore and many countries where there is strict enforcement on headlight aiming, the cars tested will need to have a very distinct and accurate low beam aim pattern, else the car will fail inspection.</blockquote>
