Xenon Headlights vs. Bi-Xenon Headlights

Last updated on August 25th, 2018 at 04:34 pm

Xenon HeadlightsTraditional halogen headlights are losing their popularity in today’s automobiles to xenon headlights and bi-xenon headlights. This is mainly due to xenon headlights efficiency, brighter light, and longer lasting bulbs. How should we compare xenon headlights vs. bi-xenon headlights? Well, they really do not have any major fundamental differences, because they both utilize the same Xenon bulbs. The only difference is in the number of bulbs that are inside of each set of headlights. Xenon headlights are required to use two sets of bulbs just like traditional halogen headlights, while Bi-Xenon headlights need only use a single pair of bulbs.

As you probably know, drivers set their headlights to high beam in order to increase the distance of visibility, and back to low so as to avoid blinding oncoming drivers. Xenon headlights use two fixed bulbs, with one set aimed low, and the other set aimed high. Bi-Xenon headlights, on the other hand, get away with operating just two bulbs. They do this by implementing a mechanical system in order to appropriately direct the beam of light. There are basically two ways in which they achieve this. The first way is by actually moving the headlight bulb itself, so that it aims properly. The second way is by using a fixed headlight bulb with movable reflectors, which achieve the same result.

Advantages of Bi-Xenon Headlights

Bi-Xenon HeadlightsThere are a couple of advantages to using Bi-Xenon headlights vs. Xenon headlights. Because of the fact that each Xenon headlight contains two bulbs, it is more likely to fail, as opposed to a Bi-Xenon headlight which only has one bulb. This is primarily because if either of the two bulbs in the headlight set fail, the whole bulb assembly is rendered unusable. Bi-Xenon headlights are generally expected to cost less compared to Xenon headlights, because of the fewer number of bulbs in the light assembly. These factors make Bi-Xenon headlights a solid selection for most vehicle owners.

Although not very likely, Bi-Xenon headlights may possibly suffer from a mechanical failure caused by the repeated transition from low to high, and vice versa. Like all mechanical systems, bi-xenon headlights may eventually suffer from wear and tear every time they are moved. Because xenon headlights do not have any moving parts, they are therefore immune to this problem.

In conclusion, here are some key points to keep in mind when comparing xenon headlights vs. bi-xenon headlights.

– Both Bi-Xenon and Xenon headlights are identical in terms of the type of bulbs that are used.

– Bi-Xenon headlights use two bulbs, while Xenon headlights must use four bulbs.

– For low and high beams, Xenon headlights switch between their two sets of bulbs, and Bi-Xenon headlights utilize a mechanical system in order to set the beam of light.

– Due to using more bulbs, Xenon headlights are more likely to fail than Bi-Xenon headlights.

– Xenon headlights may cost a bit more than Bi-Xenon headlights.

– Because of their mechanical nature, Bi-Xenon headlights may suffer from eventual failure. This is not a concern with Xenon headlights.
