The headlights provide visibility in fog, "display" the car in the daytime, and illuminate the working areas for special equipment. The main task of the TYC brand Headlight is to illuminate the road in front of the car as brightly as possible and not blind other road users. First of all, this applies to the low beam.

The construction of the headlight

The schematic diagram is the same for all types of headlights. The design provides for the presence of 4 mandatory elements:

Body: frame thermoplastic base, in which the actuating elements are located; protects internal components from mechanical damage and moisture.

Source: End cap lamps for omnidirectional lighting effect. Light emitters are: with tungsten filaments, halogen, LED, xenon (gas-discharge).

Reflector: transforms radiation into a concentrated light beam through a chrome-plated surface. Modern cars are equipped with step-type reflectors, in which each section of the element area is responsible for its own lighting zone. There are one- and two-piece reflectors. In a two-piece design, the optical assembly consists of two components: for low beam and high beam.

Diffuser: Provides light distribution and headlamp tightness protection. The main material is transparent plastic.
