The type of headlight depends on the number of bulbs
Headlamps are divided into two types based on the number of bulbs contained in the housing.
Quad lamp is not a quad lamp
Quad lamp
A quad headlamp is a headlamp with two bulbs in each headlamp
Non-quad lamp
Non-quad headlamps have one bulb in each headlamp
Square and non-square headlights are not interchangeable because the wiring inside is specific to each type. If your car has four headlights.
Then you can use it to replace the headlights, and the same goes for non-quadricycle headlights.
Headlight type based on bulb type
There are four main types of headlamps, depending on the type of bulb used. They are
Halogen headlights HID headlights LED headlights Laser headlights
1. Halogen headlamps
Headlamps with halogen bulbs are the most common headlamps. They're an improved version of the sealed beam headlights in most cars on the road today, Ben. Older headlights use bulbs that are basically heavy-duty versions of the regular filament bulbs we use in our homes
Ordinary light bulbs consist of a filament suspended in a vacuum that lights up when an electric current is passed through the wire and heated. The vacuum inside the bulb ensures that the wires don't oxidize and snap. Although these bulbs worked for years, they were inefficient, always hot, and gave off a pale yellow light.
Halogen bulbs, on the other hand, are filled with halogen gas instead of a vacuum. The filament is about the same size as the bulb in a sealed beam headlamp, but the gas pipe is smaller and holds less gas.
The halogen gases used in these bulbs are aussie and iodide (a combination). These gases ensure that the filament does not thin and crack. They also reduce the blackening that usually occurs inside the bulb. As a result, the filament burns hotter and produces a brighter light, heating the gas to 2,500 degrees.
