Safe and Classy HID Lights for Your Car

By Randy Johnston


In the United States of America and Canada, conventional halogen headlights are steadily being replaced by HID bulbs as more vehicle owners are looking to improve the outward appearance of their automobile as well as giving it a performance boost.

Composition of HID bulbs

HID stands for High Magnitude Discharge and refers back to the way in which light is produced by the bulb. HID bulbs have no metal filament but instead , around 20,000 volts is used to fire up the xenon gas and metal halide held inside a sealed glass tube between two electrodes above the base of the bulb. A car's ordinary voltage is twelve volts so a ballast is used to generate the extra first power to illuminate the bulb. The light produced is three times brighter than a halogen bulb.

Advantages of using HID bulbs - safety

Not only do HID kits improve the outward appearance of your auto, they are also a safety feature. HID bulbs are 3 times brighter than normal halogen headlights. This gives a noticeably clearer view of the road which is especially handy for travelling at night and in the rain. According to stats, 60 p.c of accidents which occur at night spring from poor lighting. Studies conducted on drivers ' reaction speed to highway stumbling blocks using halogen lamps and HID bulbs found that drivers were faster and more correct in responding to hindrances when their vehicles were fitted with HID headlight bulbs.

Advantages of using HID bulbs - potency

The bulbs are also terribly durable, being engineered to last up to ten times longer than conventional halogen headlights. HID bulbs have a standard life span of three thousand hours compared to a halogen bulb which lasts around three hundred hours. They are also shock-resistant as there is not any filament in the bulb since the light emits from plasma material. The ballasts also forestall dust and water from entering the HID bulb. HID kits are also energy-efficient since less power is required compared to normal halogen bulbs. Reduced energy usage means less fuel is being used and so cars with HID light bulbs are far more environmentally friendly as they emit less carbon-dioxide.

Size, brightness, colour and cost considerations when buying HID bulbs

Before purchasing a HID kit, you need to discover the H number of the halogen bulb employed in your automobile. Bulb fitment plugs come in sizes from H1 to H12. They refer to the sizes of the bulb holders in autos and differ to guarantee the HID bulb you buy fits.

The letter W represents watt which is the unit of power. The higher the wattage, the more power the bulb will use. Since HID bulbs are awfully bright, a 35W bulb is satisfactory and gives greater illumination than a typical halogen bulb of 55W.

There are several color options which are decided by the temperature at which the xenon gas inside the HID bulb burns. The temperature is implied by a K on the bulb which stands for Kelvin as the unit of measurement. a 6,000K HID bulb means the gas inside the bulb burns at 6,000 degrees Kelvin. Hid kits vary in colour/temperature from 3,000K "10,000K. The higher the Kelvin (K), the dimmer or bluer the light will be. 3,000K produces golden yellow, white with 4,300K "5,000K, diamond white with 6,000 K; higher than this gives ice burg blue at 8,000K, brilliant blue at 10,000K and an interesting violet at 12,000K. The most popular range for HID bulbs is from 6,000K "8,000K as they most closely resemble sunlight.

HID bulbs cost seriously more than halogen bulbs but then this must be balanced against their increased durability and the advantages they offer drivers as well as their stylish appearance.
