It is very important for a vehicle of any kind to have headlights as they are used to provide illumination at night or in poor visabilty so that you can see where you are driving. Without them driving would be quite difficult.

There are different parts to a headlight. The headlight assembly is the entire housing that the bulbs are placed in.

The headlight lens which would just be the front glass or the plastic to change or alter the look of the vehicle.

When buying a headlight assembly, you would buy them for each side of the vehicle – either a right or left assembly as they are not usually sold in pairs. Whereas headlight sealed beams or bulbs are sold either individually or in pairs.

There are many different types of headlights for many different types of vehicles, so depending on the year of the vehicle that you have, it may have:

Sealed beam headlights

Replicable halogen bulbs

HID headlights.

Sealed beam headlights are more often used on older vehicles and they are the dimmest of all the headlights that you can get. If you upgrade to halogen headlights you will be able to get more light in many different styles from:

Super white

Blue

Purple

Yellow

But it will all depend on what headlight bulbs you decide to get.

The best headlight is a HID or a High Intensity Discharge headlight. These can sometimes also be called Xenon headlights. These are the brightest lights and they will light up the most area that you can get. You will also find that HID headlights will usually have either a purple or a bluish tint to them.
