The Headlight Bulb is a part of your vehicle's front illumination system. It is the main part of your headlight assembly and illuminates the road in front of the vehicle in the dark or during heavy fog/rain. The most popularly used headlight bulbs are the halogen bulbs and the high intensity discharge (HID) bulbs. The halogen bulb consists of a tungsten filament and is a filled with a halogen element like iodine or bromine. The halogen cycle that allows for the redeposition of the tungsten on the filament, and thereby extending the life of the filament, makes the halogen bulb last longer.
High intensity discharge bulbs do not use a filament, but emit light through the generation of an electric arc between two electrodes contained within a transparent tube of fused quartz or alumina. The tube is filled with gas and metal salts which help initiate and sustain the arc within the bulb, respectively. HID bulbs are alternatively called "xenon headlamps". Your vehicle's headlight bulbs are highly susceptible to damage especially during a crash, or in some cases, when the filament gets blown due to a fault in the wiring or the relays. You should replace damaged headlight bulbs at the earliest to avoid placing yourself and other drivers at risk both at nighttime or in heavy weather conditions.
You can select the right type of bulb for your vehicle with both longevity and cost as deciding factors. HID lamps, despite being longer-lasting than tungsten bulbs, have a high glare effect. Therefore, vehicles with HID bulbs also need to be fitted with automatic beam levelers and lens cleaning components.
