What are Xenon headlights? 

Xenon headlights have been around since the early 1990s and have been growing in popularity ever since. You'll be able to spot these headlights easily on the road, thanks to their ice white/blue tint and extreme brightness. But how exactly do these headlights work?

Xenon HID (High Intensity Discharge) bulbs are filled with Xenon gas and contain two electrodes - one on each end of the tube-like bulb. When the bulb is switched on, an electric current passes between the two electrodes and the Xenon gas lights up. The Xenon gas is actually only used during the start-up of the bulb. Once the desired temperature inside the lamp is reached, other gases inside the bulb ensure it stays lit.

If your car normally uses halogen bulbs, you won't be able to easily switch your existing bulbs to Xenon HID. The bulbs themselves work in a different way, meaning that halogens and HIDs have different shapes and connect to your car differently. Take a look at the differences between a Xenon HID and a halogen bulb below:

If you're set on using HIDs in your car, you can use a HID Conversion Kit, which allows you to convert your halogen headlights to Xenon HID. These kits are not road legal and can damage your vehicle if bought from a non-reputable seller. If you wish to purchase a HID Kit, we would strongly recommend buying from a trusted supplier.

Be careful when purchasing Xenon HID bulbs. Some bulbs are marketed as using Xenon gas, but these may simply be halogen bulbs that use Xenon gas to give them a boost of white light. A good way to check if you're looking at a halogen or a Xenon is to go by fitting. If the fitting begins with a 'D' (for example, D2S), you're looking at a Xenon. Bulbs with a 'H' at the beginning of the fitting (e.g H4) are halogen.

There are also lots of counterfeit Xenon bulbs on the market which can easily fool even the savviest of bulb buyers. Always buy Xenon HIDs from verified sellers to protect yourself and your car. Read more about counterfeit bulbs here.


What are the benefits of Xenon headlights?

The first and most obvious reason why people prefer Xenon HID over other headlight types is brightness. Xenon bulbs are much brighter than halogen, which helps you to see further and better during night time driving. 

Xenon bulbs can also produce higher colour temperatures than halogen. Halogens become non-road legal when they reach a colour temperature of 4300K, and are limited in terms of producing a bluish light. However, HIDs can reach much higher colour temperatures easily whilst remaining road legal. This means that you can achieve a very strong, stylish ice white/blue light on the road with a Xenon bulb.

The final advantage of Xenon HIDs is their longevity. Xenon bulbs last much longer than halogen, which means that you don't have to worry about replacing them as often. This has the potential to save you money in the long run. However, please note that an individual Xenon bulb will cost you more than an individual halogen bulb.

Are they worth it?

Many drivers want to know if Xenon bulbs are worth the money. We think they are! You'll benefit from a strong, bright white light that offers both style and safety. Plus, you don't have to worry about replacing them as often - win win!
