What lights should be used when preparing to pass through an intersection?

Preparing to pass through an intersection requires the use of low beam headlights. Below is an introduction to vehicle lights: 1. Introduction: Vehicle lights refer to the lamps on a vehicle, serving as tools for road illumination during nighttime driving and as signaling devices for various vehicle movements. 2. Classification: They are generally divided into headlights, taillights, turn signals, etc. 3. Principle: The principle involves resistors generating heat when current passes through them, emitting blackbody radiation in the visible light spectrum when the temperature is sufficiently high. When vaporized tungsten atoms encounter the cooler outer shell of the bulb, they condense and deposit, eventually forming a blackened tungsten film on the bulb's outer shell over time.
When driving, I always turn on the turn signal well before approaching an intersection—it's a fundamental safety habit. Whether turning left, right, or going straight, signaling lets other drivers and pedestrians clearly understand my intentions, avoiding sudden movements that could cause collisions. I've personally experienced several close calls when turning without signaling, especially at night when visibility is low, making it even more dangerous. So, I make it a point to signal about 30 meters before the intersection to give ample reaction time. Developing this habit is simple and effective—don't skip it out of laziness. Additionally, in rainy or foggy conditions, turning on headlights increases visibility, but at intersections, turn signals remain key for indicating direction. Consistently doing this adds an extra layer of road safety. Before every drive, I also quickly check if the turn signals are functioning properly and replace any burnt-out bulbs promptly.
