High Intensity Discharge (HID) projection headlamps

High Intensity Discharge (HID) headlamps that produce a bluish white beam of light are common on luxury cars today. They operate at higher voltages than traditional headlamps and use xenon gas for operation. Also, unlike traditional headlamps which use filaments, HIDs use two electrodes to produce light.

HID headlamps are available in the aftermarket priced upward of Rs. 5,500 (each) and can be fitted to any vehicle. There are also normal incandescent headlamp bulbs in the aftermarket with blue glass or a blue coating that produce a bluish beam, however, they are no brighter than regular headlamp bulbs.  

The advantage of using HID projection headlamps is that they provide a clearer and longer field of vision in the dark, useful during high speed driving at night while also enhancing road safety due to better visibility.

Installing aftermarket HID projection headlamps will greatly enhance your field of vision at night by providing consistent white light with a much longer field of view.

The downside is that HID projection head lamps are extremely bright and cause glare at high beam. This is why car manufacturers fit HID head lamps with an automatic beam leveller that adjusts the beam according to the tilt angle of the vehicle via sensors on the front and rear axles of the vehicle. However, after market HID projection head lamps do not come with such a feature and hence can cause inconvenience to other road users.

The other major downside of HID projection headlamps is that they are very expensive due to the technology used.
