Headlight is Powerful light at the front of a vehicle. One car usually needs a pair or two pair of bulbs. It is depend on the original car design. Driver need power light to illuminate the road in front of them to keep them safe, so the halogen bulbs are usually been used as headlight. Halogen bulb can generate more light and has better working life hours. The supply voltage of halogen lamp is usually divided into ac 220V and dc 12V and 24V. The halogen lamp is made of tungsten, but it is enclosed in a smaller quartz glass shell. Normally, the halogen bulb will create ultraviolet when light, so we must use quartz coating to prevent head lamp been damaged by the ultraviolet generated by halogen bulb. To generate more light, the filament be heated to the very high temperature, so halogen bulb is hotter than a normal bulb.
