What kind of light is the yellow light?

Yellow light refers to xenon headlights with a color temperature of 3000K. Below is an introduction to xenon headlights: 1. Introduction: Xenon headlights, also known as HID (High-Intensity Discharge) headlights. They replace traditional tungsten filaments with xenon gas encapsulated in quartz tubes, providing higher color temperature and more focused illumination. Xenon headlights generate an arc of light by activating xenon gas with high-voltage current, enabling continuous light emission between two electrodes. 2. Structure: HID xenon headlights generally consist of a lamp head and an electronic ballast (also called a stabilizer or voltage regulator). 3. Principle: The illumination principle of xenon headlights involves filling a VV-CUT ultraviolet-resistant quartz glass tube with various chemical gases, predominantly xenon and iodides, and then using a booster to instantly increase the vehicle's 12V DC voltage to 23,000V.
In my driving experience, yellow lights are primarily the vehicle's turn signals and hazard warning lights. They are usually located at the front and rear of the car, serving to alert other drivers that you are turning or that there is a hazardous situation. Yellow was chosen because it stands out particularly well in poor weather conditions like rain and fog, unlike red brake lights which can be easily overlooked or confused. I remember one time driving in heavy rain, the flashing yellow turn signal of the car behind us helped us avoid a potential rear-end collision—I was really grateful for these design details. I usually teach my friends to regularly check these lights, such as inspecting the bulbs themselves to see if they are burnt out or have poor contact, ensuring safer driving. This not only prevents accidents but also gives everyone more confidence when driving at night.
