Xenon Headlights vs. Bi-Xenon Headlights – Which Is Best?

In the current automobile world, the traditional halogen headlights are slowly losing their popularity to the Xenon and Bi-Xenon Headlights. This is mainly because the xenon headlights are efficient, last longer and are brighter than other bulbs. Xenon bulbs are however classified into two. There are single beam headlights, and dual beam headlights. Dual beam headlights are further broken down into Hi/Lo bulbs and Bi-Xenon bulbs.

The choice you make between the two will greatly depend on your vehicle as well as reference. In the even your car requires a single bulb for the high beams and yet another for the low beams, then your car has a single beam bulb. If your car, or the car you intend to purchase has a single bulb for those, then you are looking at a dual beam bulb.

What are Xenon and Bi-Xenon Headlights?

#1. Xenon Headlights

Now Xenon headlights have a different working mechanism from regular halogen headlights. In Xenon headlights there are no filaments. Instead, the bulbs feature xenon gas and electrical charges that together work to produce light. The electrical charge excites the xenon gas particles to produce a bright white light. The light produced is brighter than that of halogen headlights.

These units are also efficient and long lasting. They are made suitable for amateur installation and anyone can perform the installations without any technical know-how. These are graded according to the lumen and temperature output.

The temperature denotes the color of the light produced by the bulbs. These colors range from dim yellow all through to a brilliant white and into vibrant purples and blues. The lumens determine the level of brightness of the bulb and are inversely correlated to the color brightness of the bulb.

It is also worth noting, as earlier state that xenon bulbs can either give you a high illumination of a low illumination.

#2. Bi-Xenon Headlights

These are essentially the same to xenon bulbs. The technology that they use is the same and the efficiency and durability is equal as well. What distinguishes the two is the ability to provide both hi and low illumination through one bulb. Bi-Xenon bulbs are designed in a way that they can pull this off.

Instead of having a single xenon gas capsule serving either as a high or low illumination unit, they feature two Xenon gas capsules. When the low light beam is switched on, the light is reflected to the low light capsule at an angle only illuminating the lower path and when the high beam light is switched on the beam reflects at a higher angle thus producing a high beam of light.

Advantages of Bi-Xenon Headlights

Using bi-Xenon bulbs has a couple of advantages over Xenon headlights. The fact that Xenon headlights come with two bulbs make them slightly susceptible to failure in comparison to the Bi-Xenon bulb which only features a single bulb that provides both high and low light beams. In a xenon bub, if a single bulb of the two fails, then the entire bulb is rendered useless. With this unit, it is all or nothing.

In addition to this, the Bi-Xenon headlights are considered to cost less in comparison to the Xenon headlights courtesy of the fewer bulbs in the unit. These factors make the Xenon bulb more solid and a preferred choice by many car owners.

With the Bi-Xenon units you have great convenience than with the Xenon headlights. Here is why. With a flip of a lever you get to switch between high and low beams as the situation dictates. During installation, the Bi-Xenon units are easier to install since you will only be installing a single bulb.

Disadvantages

When you consider the working mechanism of Bi-Xenon headlights, you will understand one thing, they are a bit more mechanical than Xenon bulbs. When changing from high beams to low beams and vice versa a lever has to be switched which alters the positioning of elements in the unit which in turn provides the desired effects.

While this is convenient, these B-Xenon headlights are susceptible to mechanical failure like any other mechanical gadgets. With moving parts, the unit becomes all too vulnerable compared to Xenon bulbs that have different bulbs for the different beams.

With time, with constant moving, wear and tear takes place in the moving parts and the unit eventually breaks down. Xenon bulbs are immune to this issue courtesy of their lack of moving parts.

Conclusion

Both headlights will serve the need you have at hand. However, one proves to be more efficient in getting the job done than the other. The choice of the product you make greatly depends on your preference but you still have to bear in mind the minor differences that make a big difference. If you are running halogen lights, be sure to transition to Xenon headlights.
