What does the car position light mean?

[VanDaniel]

Car position lights are the four flashing lights (front, rear, left, and right) that activate when the hazard warning lights are turned on, also known as vehicle width indicator lights. They are primarily used to alert approaching vehicles and are suitable for nighttime driving. Below is relevant information about automotive lighting: 1. Basic Introduction: Automotive lights are various traffic lights installed on vehicles to ensure safe driving, divided into two categories: illumination lights and signal lights. From 1905 to 1912, to address road illumination ahead, acetylene headlamps with spotlight features began to be installed, accompanied by a kerosene lamp serving as the rear license plate light. By 1945-1947, the minimum required assortment of external lighting fixtures had been finalized. Qualified automotive lights must comply with corresponding photometric, colorimetric, and basic environmental testing standards. 2. Development Trends: Specially shaped headlamps that align with streamlined vehicle body designs will continue to evolve, with high-intensity discharge (HID) lamps potentially becoming the new generation of headlamp light sources. Research is ongoing to improve high-mounted brake lights and high-contrast combination rear lights.
