Headlights are designed to give you maximum visibility while driving your vehicle. They light the road in front of you when it is dark out, and can even be used to improve visibility during adverse weather conditions. Just as importantly, headlights make your vehicle visible to oncoming traffic, which is vital for your safety on the road.
The 3 Types of Headlights
Halogen headlights are an improvement of incandescent lights (sealed beam lights). Incandescent lights are still used for classic cars. With that said, Halogens have truly taken over as the standard in most vehicles.
There are five halogens, however, only two are used in halogen headlights: Iodine and Bromine. Halogens are monovalent elements and they readily form negative ions. Halogen lights use a combination of iodide and bromine gases that prevent the tungsten filament from breaking. They also prevent suit formation (blackening) inside the bulb.
Halogen lights produce a lot of heat as electricity flows through the filament and lights up the bulb. The heat production makes handling these bulbs quite difficult. Even small amounts of moisture from your skin can diminish how they perform.
2. Xenon, HID, Arc
Xenon or high-intensity discharge (HID) lights don’t use a metal filament to create light. These lights create a high voltage arc between two electrodes. You can think of this like a controlled bolt of lightning happening inside a small tube.
The HID bulb is filled with xenon gas. As the xenon gas ignites it produces a bright white/bluish light. This process creates far less heat in comparison to halogen. However, in order for the lights to come to full brightness, they need time to warm up. Once they are warmed up they are quite bright.
LEDs or light emitting diodes are popular in newer cars. Retrofitting LED headlights is also very easy and the upgrade only takes 30 minutes.
These lights work by converting electricity into light through diodes inside the headlight; the process is known as electroluminescence. This process is also more energy efficient compared to halogen as little to no heat is created. This means that the lights are able to last a lot longer.
LED headlights are going to be a bit more expensive. They also last longer and the intensity of their light is stronger. This means your downroad visibility is improved and you’re safer on the road. The light is also tolerable for other drivers.
Benefits of LED headlights
For side and reversing lights, LEDS give out a crisp, white light. All light has a “colour temperature”, which is measured in kelvins. The higher the colour temperature, the whiter the light. For example, a standard bulb has a colour temperature of around 2700 kelvins, which is a warm, yellow-toned white light. A white LED has a colour temperature of around 6000K, which is a much crisper, blue-toned white light. This whiter light gives vehicles a high spec look and is excellent for colour matching to daylight running lights.
Light is measured in lumens, and a higher lumen rating equals a brighter light. LED Car headlights can be just as bright – or brighter – than standard bulbs.
Lower risk of a flat battery
Because LEDs draw less energy from the battery, if you accidentally leave a light on it’s less likely to drain your battery. Handy if you have a habit of leaving the interior light on.
- Longer Life
- Less Power Usage
- Greater Clarity
- Installation Can be Tricky
- A little bit more expensive than regular headlights
Top LED headlights are up to 80% more energy efficient than their halogen counterparts, and they will keep your car battery healthy. Not only are they powerful, but they will last 5 times more than regular headlights. LED headlights are available for purchase at Banggood.com
