An automotive headlight system typically consists of various lighting fixtures. The following are common headlight components and their functions:

High beam: It provides strong illumination at night and in case of poor visibility. It features a longer range of illumination, but may cause glare to drivers of oncoming cars.

Low beam: With a wider illumination range, it is mainly used to reduce glare to other drivers on urban roads and when other vehicles approach.

Daytime running light (DRL): It is turned on during the daytime to improve the visibility and safety of the car. The daytime running light typically has lower brightness and cannot replace low beam.

Turn light: It is usually located on the side or bottom of the headlight, and is used to indicate the direction in which the car will turn or change the lane.

Fog light: It is usually located under the front bumper, and serves the purpose of enhancing lighting in weather conditions with low visibility such as fog, rain, or snow. The light it emits is typically horizontal, which can reduce light reflection and improve road visibility.

Marker light: It is a small light (such as a position light) provided in the headlight system of some car models. It is used to increase the visibility of the car during parking or at night.

Automatic adjustment light (such as adaptive headlight): Some modern cars are equipped with an adaptive headlight system that can automatically adjust the direction of beams to adapt to the driving direction of the car and road slope for higher driving safety. 

The combinations and functions of these lighting fixtures vary depending on the vehicle models, but they share the same purpose of contributing to better visibility and driving safety.

Advantages of DPA headlight:

1. Lamp shade: The DPA lamp shade is made of imported Bayer PC material and based on a dual-color molding process. The surface is coated with imported UV hardening material, which features excellent resistance to UV and oxidation, preventing any yellowing in the first 2 years of use, leading to good light transmittance, and contributing to safe driving.

2. Lamp shell: The lamp shell is made of original PP material that is not easily oxidized and not fragile.

3. Lamp bowl: The lamp bowl is made of new material BMC characterized by high rigidity and strength, good forming shrinkage ability, and high dimensional accuracy. It effectively ensures the stability of light beams.

4. Lamp bulb: The light bulb harness is an original product with more stable quality, safter operation, and longer service life.

Core problems solved by DPA headlight: lamp shade yellowing and water ingress.
