![]() ![]() There is no tungsten filament in the bulb body, so the HID can be used for a longer time. It breakdowns the xenon by high pressure to produce an arc between two electrodes to light up the bulb. ![]() The HID bulb is full of Inert mixture gas includes Xenon. So it does not work well the projector but performance better in the reflector. However, a halogen bulb is not bright enough when working with the projector, it is going to be dimmer than before. Later then some car manufacturers create a projector for replacement of the reflector to improve the headlight appearance and the spotlight ability. So people made a reflector to spot light beam. Since the light emits from halogen bulb is in 360 degrees, it can not be focused that would cause dazzling oncoming traffic on road and waste lots of effective light. For the result, the halogen bulb life-span takes longer than the incandescent bulb. And then will resolidify on the tungsten filaments to reach a balanced cycle to avoid fracturing. The sublimed tungsten filaments get a chemical reaction with halogens at high temperatures. In order to improve the incandescent bulb durability, people input halogen gas into the bulb, so the halogen bulb comes out. The incandescent light bulb is an electric light with a wire filament heated to such a high temperature that it glows with visible light, but the lifespan is too short. Today, we would like to talk about the four important headlight bulb in the headlight history.īefore talking about the halogen bulb, we need to know about the incandescent bulb. Many car owners upgrade their car lights with different headlight bulbs to reach their lighting requirement. John has 20+ years experience in the industry and in that time has become an approved partner of Philips and OSRAM.In the current Headlight aftermarket, there are many types of headlight bulbs such as HID bulb, LED bulb are used for retrofitting. John Conboy is the founder of, a UK based automotive lighting specialist, which ships bulbs worldwide. Considering all of this, it's clear that projector headlights are better than reflector headlights.ĭid you enjoy this article? Do you have any further information that we've missed? Please let us know via our Facebook page. It's also worth mentioning that projector headlights allow drivers to use xenon HID bulbs instead of the older halogen bulbs. Projector headlights are brighter than reflector headlights, and they are less likely to blind oncoming traffic. When searching for the best headlights, most drivers want the brightest headlights possible without creating problems for other drivers. HID bulbs are too bright when used in reflector headlights, where the light they emit can blind other drivers. Xenon HID bulbs can only be used with projector headlights. Reflector headlights can have darker spots. Projector headlights give off a more even light. Because projector headlights are directed downwards towards the road, they don't shine in other drivers' eyes. They're less likely to blind other drivers. Projector headlights are significantly brighter than reflector headlights. Projector headlights are growing in popularity, and for good reasons. Thanks to the shield, projector headlights have a very sharp cutoff. This helps to direct the light down towards the road. To ensure that the light produced by these types of headlights is angled properly, there is also a cutoff shield. However, a projector headlight also has a lens that acts as a magnifying glass, increasing the brightness of the light beam. They contain a bulb in a steel bowl with mirrors to act as reflectors. Projector headlights are similar to reflector headlights. Since then, projector headlights have become popular on all types of vehicles. They were first used on a large scale in the 1980s in some luxury vehicles. Projector headlights are a newer invention in the world of headlight technology. Projector headlights are deeper, taking up more space within the vehicle. Manufacturers often use reflector headlights simply because they're less expensive. There are a few advantages to this style that make them popular even today: Many new vehicles continue to be made with reflector headlights. This meant it was no longer necessary for the lens and the headlight housing to be sealed, and bulbs could be easily removed or replaced. In the 1980s, improvements in technology led to reflector headlights that used mirrors inside the headlight housing itself to guide the beams. With this type, known as a sealed-beam headlight, the casing cannot be removed to replace a burnt-out bulb. In older reflector headlights, the shape of the light beam was determined by the lens in the front of the headlight. ![]() Mirrors are place within the bowl to reflect light out onto the road. A reflector headlight consists of a bulb encased in a steel bowl. Reflector headlights have featured as standard on vehicles since the invention of electric headlights. ![]()
