Different countries have different languages and different customs. Likewise, there are differences between countries when it comes to road driving. Car manufacturers will adjust the driving position, interior configuration, front-end status, etc. according to the road regulations and driving habits of each country. Then, the corresponding required automotive accessories will also be adjusted accordingly.
Automotive lighting system, as the eyes of the vehicle, play a vital role in safety and functionality. This article will discuss car road habits,automotive headlights light type, etc.

Hot knowledge: left-hand drive vehicles and right-hand drive vehicles
What is left-hand drive(LHD)?
What is left-hand drive(LHD)?
Left-hand drive means that the driving position of the car is on the left side of the vehicle and the vehicle drives on the right. The reason is that it is convenient for the right hand to shift gears and conforms to the thinking habits of the right hand.
What is right-hand drive(RHD)?
What is right-hand drive(RHD)?
Right-hand drive means that the driving position of the car is on the right side of the vehicle and the vehicle drives on the left. The reason is that when encountering danger, people's reflex conditions agree to turn to the right to protect the heart.
What is the automotive headlight cutoff line?
The automotive headlight cutoff line refers to a clear dividing line formed by the edge of the beam when the car light is illuminated. It is usually used to control the projection range and shape of the car light light.

Why should we design the cutoff line?
Engineers used optical principles to design light and dark cutoff lines to divide bright and dark areas to help identify pedestrians or roadblocks on the left or right side and avoid dazzling oncoming vehicles.
Learn about Low-beam light patterns for left- and right-hand drive vehicles
- Characteristics of left-hand driving lights: low on the left and high on the right.
1. Features: Most appear in countries that drive on the right
2. Function:
Avoid dazzling drivers of oncoming vehicles. On national roads that drive on the right, the left side of the vehicle is usually the direction to meet oncoming traffic. The function of lowering the light pattern on the left is to prevent the light from affecting the field of view of the driver oncoming traffic, so that it will not be dazzling and dazzling, so as to avoid the occurrence of traffic accidents.
Better light the right side of the road. The headlight beam on the right side is higher and can better illuminate the road surface, signs and obstacles on the right side of the road. This is especially important for spotting pedestrians, animals or other potential hazards.
Comply with regulations and good standards. Most countries and regions have clear regulations and standards for the light pattern of vehicle lights. The lights of left-hand drive vehicles must be designed to be low on the left and high on the right.

Question: "Why do I see that some car lights have different standard light patterns?"
Answer: In fact, according to the tangent of the light type, the standard light type can usually be divided into three categories: American standard light type, European standard light type and mixed standard light type. The following introduction takes the light pattern of the left driving light as an example.
American standard light type: American standard light type (DOT) adopts a slanted stepped design with little difference between left and right, and the angle of illumination is wider. It has obvious advantages in suburbs or some places with poor road lighting conditions.
European standard light type: The left side of the European standard light type (E-mark) is horizontal, and the right side is tilted upward for a longer distance, with a large up and down range, and there will be more dark areas on the left side.
Mixed standard light type: Mixed standard light type combines the characteristics of American standard and European standard light types. It can better take care of the target vehicle's field of vision without causing too many dark areas on the left side.
Additional knowledge: Which countries use left-hand drive and which countries use right-hand drive?
According to incomplete statistics, most countries use left-hand drive. Mainly include: China, Canada, Germany, Russia, Philippines, Brazil, Italy, France, Spain, etc.
Of course, due to differences in geographical environment or local construction thinking. Some countries use right-hand drive. Mainly include: United Kingdom, Australia, New Zealand, India, Indonesia, Thailand, Malaysia, Singapore, etc.

Expand your knowledge: Drive on both sides
Meaning: "Drive on both sides" refers to situations where driving on both sides of the road is required under some special circumstances. It usually occurs in border areas or traffic transition areas in some countries, but it is not a standard driving rule.

Light shape characteristics of cut-off line for drive on both sides: flat straight line
Reason: Motor vehicle lanes in some countries and regions are not completely one-way streets, and flat and straight headlight cutoff lines can be used for multiple vehicles traveling side by side.
In some specific driving environments, such as city streets, parking lots, etc., the driver needs to keep the vehicle traveling on the same level and not veer to one side. Therefore, flat straight line are chosen when using car lights, which helps avoid collisions with other vehicles or objects, especially in environments with limited space.
In addition, in most cases, fog lights are often in the form of flat straight line. Of course, it is understood that flat straight car light styles are also very popular in some parts of Indonesia.

Additional knowledge: automobile LED light color temperature
Meaning：Auto light color temperature refers to the color of light emitted by the car light source, usually expressed in Kelvin (K). Color temperatures with different values will present different light sensations and colors. Lower color temperatures (e.g., 2000K to 3000K) typically exhibit warm tones, similar to yellow; higher color temperatures (e.g., above 5000K) typically exhibit cool tones, resembling blue-white light or cool white light, similar to light in sunlight.
Regarding the color temperature of automotive led lights, we have published a special blog article. You are welcome to browse our blog. I believe you will gain something.
