What are the Different Types of Headlights and Bulbs?

Headlights are important for driving at night and in bad weather conditions. It is very important to have working headlights on your car. If your headlights are not working, you should fix them as soon as possible. You can find different types of headlights to buy today. In order to understand which headlights are right for you, you should look at the headlight bulb types chart on bulbsizechart.com.

4 Types of Headlights and Headlight Bulbs

There are four common headlight bulb types. Halogen, LED, Xenon/HID, and Laser. You will have to choose which headlight bulb is the right one for you.


Halogen headlamps contain a tungsten filament or a pair of filaments on single bulbs. The headlamp bulbs are pressurized with gas and a small amount of chemically reactive halogen gas, usually iodine or bromine.

This allows headlamps to burn brighter and longer without blackening the inside of the headlight bulb. Some headlamps have a blue coating to make them appear brighter than they are.

Halogen headlight bulbs are the most common type of headlight bulb. They use a gas called halogen to make them brighter. Some older headlights used a type of bulb called a sealed beam.

If one of those broke, the vacuum inside the sealed beam lamp would be lost and the old-style filament would oxidize and burn out quickly. With the halogen capsule providing light, a small rock hole in the lens facing doesn't matter.

Halogen headlight bulbs are a type of headlight bulb that is less expensive to replace than some other types of headlight bulbs. Most people only pay around $20 to replace them.

They are usually easy to replace, but you need to make sure you buy a good brand name. Some brands may not last very long.


LED headlight bulbs create light by using a process called electroluminescence. This means that electrons are shot towards positively charged holes in a semiconductor, and when they hit, energy is released as photons-particles of light.

LED lights are now used for things like dashboard lights, screen consoles, appliance indicator lights, bright flashlights, and vehicle stop lamps.

LED bulbs are small semiconductors that can be arranged in tight spaces. This means that manufacturers can design sleeker headlight assemblies and be more flexible in styling other assembly components, such as turn signal lights.


Some headlight bulbs are called Xenon. They give off a very bright light that is good for night driving. Some headlight bulbs use a mix of gases and metal vapor to create the light. You can buy headlight bulb conversion kits from stores if you want to upgrade your car headlamps with Xenon/HID headlights.

HID headlights emit light in a color scale of blue-white. A higher number means that the light is stronger, so it can illuminate more things.


Laser headlights are a recent innovation in automotive lighting technology. These lights work by shining a light through a chamber which makes the phosphorus gas inside glow. The light that you see in front of your car is coming from the gas, and not the laser beams themselves.

Within the headlight unit, lasers shine onto mirrors which reflect onto a lens filled with special gas to create a strong light beam.

Laser headlights are better than LED lights. They can produce 1,000 times the light for half the amount of energy LEDs use. They are smaller and easier to make holes in. Plus, they can be switched on/off.
