Headlights. What I Should Know!

The world of headlight technology is moving rather rapidly. It was customary for all vehicles back in the day to come with halogen headlights and nothing else. Today, there are so many more options, including xenon and LED lights. It is important to know what works best for you and your car.


Halogen is the most popular type of headlight bulb currently on the road. They account for most of the bulbs you see on the streets on Accra and all around the country. The bulbs are cheap to manufacture, thereby making them cheap to buy plus they’re very simple to replace on most vehicles. Inside the bulb is a filament made out of tungsten and halogen gas. The bulb lights up when electricity reaches the filament, heating up the tungsten which begins to glow.


Xenon HID bulbs are not a bad option. They are becoming increasing popular on the local market. They however come standard on many high-end vehicles, giving that elite, premium and stylish look that some halogens can’t achieve (Definitely not). Xenon bulbs can produce a brighter, whiter light than a halogen bulb, and tend to have a longer lifespan.

HID stands for High-Intensity Discharge. The bulb works in a different way to a halogen. Instead of a filament heating up and glowing, HID headlights use electrodes to charge the gas inside the bulb. This produces the light you see on the road. Xenon bulbs can produce a brighter, whiter light than a halogen car, and tend to have a longer lifespan.

One flaw with xenon headlights is that they take a little while to reach full brightness when you first switch them on. They also need to be in use for a while to shine as bright as they should and can

What are the advantages of xenon?

In addition to the better vision, xenon lights also use less energy, and because they have no filament to wear out, they are longer-lasting. In some modern cars, they also come with automatic height adjustment to align the lights to suit the load the car is carrying.


LED car bulbs are a recent development in the industry. These bulbs are proving to be very popular as they can produce an extreme white light. Plus, they’re much more efficient, due to their long lifetime and the low wattage they require to work.

LEDs use negative electrons to generate photons. This happens very quickly – thousands of times per second – which is how a continuous, strong light is produced. As the bulbs themselves do not have a filament, LEDs technically have no parts that wear down over time, meaning that they last much longer than Xenon or halogen headlight bulbs.

What are the advantages of LED lights?

They produce a whiter light than a halogen bulb, LED lights use much less energy (leading to better fuel consumption and lower emissions) and last much longer, because there are no internal parts to wear.
