Types of Car Headlight Bulbs and Lighting Technologies

Lighting is one of the essential points for the safety of a car. In fact, in addition to guaranteeing good visibility of the road for the driver, it also allows the latter to see all road users from afar and thus avoid accidents and nests. In this article, we take stock of the different types of lighting technologies or Car Headlight Bulbs and more specifically, headlight bulbs to better illuminate your choice of bulbs at the time of your purchase.

Different types of Car Headlight Bulbs

So far, there are five types of headlight bulbs for vehicles: Halogen bulb, xenon bulb, LED bulb, laser headlight, and OLED bulb.

1. The halogen bulbs

This is the type of bulb that was most common in the 90s and is still found in many used cars. There are particularly three types, H1, H4, and H7, the latter is the one that is most often encountered. The halogen bulb has the advantage of having a good price.

Disadvantages: The halogen bulb has several drawbacks, particularly in terms of its lighting which is both old-fashioned and not very bright, with a range of only 150 meters. In addition, this bulb has excessive consumption and is very fragile.

2. The xenon bulbs

This bulb takes its name from the gas that powers it, xenon. Appeared in 1991, this type of bulb has since spread to high-end cars. Its peculiarity is its white-blue lighting. Durable and powerful, the range of the light beam of this bulb is estimated at more than 200 meters.

3. Xenon bulbs

Disadvantages: Even if it has several advantages, the xenon bulb has the ironic disadvantage of being so bright that it risks, on the contrary, blinding other road users even if it tires the driver’s eyes less. Also, since xenon gas is quite scarce, the price of this bulb is expensive.

4. LED bulbs

The term “LED” stands for Light Emitting Diode, or in French, electroluminescent diode. This bulb has the characteristic of being more powerful than the halogen bulb and the xenon bulb but less dazzling than the latter, therefore less aggressive for the eyes.

It has a lot of advantages like low energy consumption, super-fast ignition, and a lifespan equivalent to that of the car. This bulb is part of the prestigious range of car headlight bulbs and is recognized for its efficiency and autonomy. The range of its luminous flux is 300 meters.

Disadvantages: Only, like the other bulbs mentioned above, the LED bulb is not without its disadvantages. Indeed, it presents the annoying tendency to overheat but above all, it endangers the other components of the car. This is the reason why this type of lighting is currently less widespread than the others.

New innovative technology for car headlights

We will not stop progress so know that manufacturers continue to search for new lighting solutions combining security and energy performance. The Audi brand is particularly at the forefront on the subject and offers new types of headlights on these latest high-end vehicles.

1. Laser headlights

It is innovative and the most recent technology. It exceeds all the characteristics of the bulbs mentioned so far. Imagine that its luminosity reaches 600 meters and that its light beam is not only more powerful but also more broadened than all the other bulbs which currently exist. In addition, do not be fooled by its small size as its brightness is four times that of the conventional LED bulb.

2. laser car headlights

Cons: This type of bulb is currently found on premium vehicles like Audi and BMW and to our knowledge, these bulbs have not yet been deployed on standard cars. These bulbs are also the most expensive on the market at the moment, due to their efficiency and performance.

3. The OLED bulb

As we said before, the laser headlight is the most expensive and efficient solution that exists on the market today. But that doesn’t mean automotive professionals are no longer looking at even more powerful technology that can surpass it.

This is precisely the case with OLED technology (organic light-emitting diodes). This technology is currently still in the prototype phase in the automotive sector. However, it can already be found on certain television models.

It differs from LED technology by the fact that it is not made up of semiconductor crystals but of flat light sources which allows it to reach a new level of homogeneity. In addition, the OLED car bulb will not cast shadows and need no reflectors.

The light source of this technology would also be light, thin, easy to install, and space-saving. And finally, it would be suitable for all vehicles without exception. We just want to see it!
