Headlights are one of the most important components in a car. Not only do they enhance beauty but also at the same time play a huge role in providing better visibility. Let us explain how they work and what their types are.
1. Halogen Bulbs
Halogen bulbs have long existed in the market. Might not be surprising to say that it is the most popular bulb type in the market. These bulbs or headlights perform similar to the bulbs found in households in the sense that they have a filament made of metal that lights up and shines brightly upon being heated with electrical current. Halogen bulbs are long lasting, cost-effective and easy to replace. One disadvantage of Halogen bulbs is that they produce yellow light. These lights will work well in foggy weather as white light bounces back in such conditions. Therefore, if it is a foggy day, you might want to turn on your halogen lights.
2. HID/Xenon Bulbs
HID or High Intensity Discharge bulbs have a totally different technology at hand. They perform very different to other bulbs in the market as it has a glass tube with Xenon gas trapped inside and the light is produced when electric power is passed through electrodes. HIDs used a ballast that happens to be an electronic circuit for controlling the electric current as well as the output. Even though they last longer than filament bulbs, HIDs hold a big disadvantage and that is they produce very bright blue light that irritates other motorists on the road.
3. LED Headlights
LED or light emitting diode, is in the game nowadays. It has rapidly gained the attention of everyone due to its numerous positive aspects and keeps on capturing consumer preferences. The first advantage is that LED bulbs last longer than other bulb types and consumer less power. These two reasons alone are enough to be used in headlights, taillights, fog light bulbs, and even indicators nowadays. LED headlights have a heat sink attached, which is basically a small fan that forces heat out to prevent damage.
Daytime running lights come factory fitted in majority of cars nowadays. These are basically LEDs that remain turned on while the car is on. Since they are LEDs, they consume almost zero to none energy and are liked mostly by people due to their styles and designs. They also tend to increase the visibility of your car during daytime.
5. Digital LED Headlights/Smart LEDs
Digital LED headlights are both expensive and intelligent. Therefore, they are only being offered on selected luxury cars such as Mercedes and BMW etc. These headlights are intelligent in the sense that they automatically by using sensors, increase or decrease light when driving on dark or visible roads. Depending on road conditions, they will automatically turn high beam on and off, if they detect an incoming driver.
Conclusion Headlight technology has evolved to new heights with so many options even for indicators and fog light bulbs. With the amount of research and technology being done to come up with new inventions in this area, you will not be surprised if something totally out of this world pops up.
