Technological developments lights mounted on the vehicle industry is highly developed. There are three basic standards applied to the front vehicle lighting products, namely the European standard (ECE), American standards (SAE) and Japanese standards.  From the optical side, there are only three kinds of lights, use a regular lens, reflector and projector.  All three have a similar scheme, but produces a different light.

Lens Optics
Light source filament or arc can be shaped, placed near the focus of a reflector, which form the complex, can be parabolic or non-parabolic.
Fresnel optical prism and the molding into the lens headlamp and can be casting light coming from the filament / arc in the bulb. Own light will glow laterally and vertically according to the pattern of optical lenses mounted on the front.  So the light and the light distribution will depend on the pattern of the lens. Lenses can be made from many materials, but the most often used is glass.

Reflector Optics
Austin Maestro 1983 are the first vehicle to be given light reflector homofocal by Luca Carello. This has the parabolic reflector with focal length to increase efficiency, collection and distribution of light. compared to an optical lens, the light pattern will be directed from the reflector design itself, not on the lens. Modern reflector made of a mixture of plastic, glass and metal. Surface reflections are other materials such as aluminum and overcoating so much brighter.

Headlamp Reflector Applications
The presence of CAD technology also makes the development of increasingly advanced reflector lamps premises, more complex but more to provide convenience to the rider. The first American car that uses complex-reflector headlamp is the Dodge Monaco. In Europe, Citroen MX, whereas in Japan, Honda Accord 1990 that the first use of multi-reflector.

Dual Beam Reflector
Driving at night can be difficult because the atmosphere is quite dark. Conventional headlamp can indeed dangerous, both for yourself and others. one problem is the glare or too bright. dimming can be done thanks to the two filaments are grown in light.

Projector Lamp
This is the latest development that is used in the headlamp. called polyellipsoidal. In contrast with the lens and reflector lamps, projectors consist of a filament is placed at one focus of a elipsoidal reflector . Then, a cross-section is placed between the reflector and lens so that light will be diverted to other points in the lens. in this section, usually placed solenoid for the lights can be divided between low beam and high beam.  Actually, Hella has introduced the model optical light elipsoidal this type in 1911 but somewhat old-fashioned technique. Only after this projector technology develops, the projector lamp can be applied in the vehicle. Audi Quartz 1981 was the first car to apply the projector lamp.
