Car light signals reference table refers to a comprehensive guide of car light signals. The following is an introduction to the car light signals reference table: 1. When the light turns green but the car in front doesn't move or when you want to overtake: flash the headlights once. This is commonly used when the car ahead is driving slowly on the road and the driver behind intends to overtake, or when at a traffic light that has turned green but the car ahead still hasn't moved, flashing the headlights once serves as a reminder to the driver ahead. 2. When encountering strong glare from headlights at night: flash twice as a reminder. This is commonly used when meeting another car at night, and the other car is still using high beams, causing glare. The affected driver needs to flash the headlights twice to remind the other driver to switch to low beams. 3. When there is a problem with a neighboring car: flash the headlights three times. This is generally used when the trunk or door of the neighboring car is open, or when the tire pressure is insufficient, to remind the neighboring car to pull over and check for potential safety hazards. 4. When a car needs to merge: a single flash indicates agreement, while continuous flashing indicates refusal. This is commonly used when a car in the same direction is changing lanes or when a car from another lane is merging onto the main road. 5. When the following car is too close: intermittently illuminate the brake lights. This is commonly used during driving when the car behind is following too closely, increasing the risk of a traffic accident, so the brake lights are used to remind the following car to maintain a safe distance.

Having driven for most of my life, I find light signals particularly practical. A single flash of the headlights means yielding or greeting, while two flashes often serve as a reminder at intersections for the other party to go first. Hazard lights are used for emergency stops, such as when the car breaks down or during heavy rain or fog to warn others. Don’t panic if the brake lights stay on continuously, but frequent flashing might indicate that the car behind is following too closely, which is dangerous. Using turn signals properly allows others to anticipate your turns or lane changes, reducing the risk of collisions. I’ve also encountered impolite high-beam flashing at night, in which case a single flash signals a request to switch to low beams. On highways, flashing hazard lights are often seen to warn of accident zones. In fact, light signals are like speaking—clear but not excessive, to avoid misleading others and causing accidents. Remember these tips, and driving will be safer and more pleasant.

I just got my driver's license not long ago, and my friends taught me that car lights can also 'talk'. Flashing the headlights when overtaking means 'let me pass', and flashing once when someone gives way is a way to say thanks. Turning on the hazard lights in emergencies signals following cars to keep their distance. If the brake lights of the car in front flash rapidly, it means they might be braking suddenly, so I should slow down. Using turn signals when changing lanes, and turning them on a few seconds earlier is even better. If an oncoming car flashes its high beams at night, it means 'too bright', so I should switch to low beams. These light signals are simple to learn and improve safety, especially in crowded urban areas during traffic jams. Communicating with lights is quite convenient and reduces the noise of honking.

After years of repairing cars, I've found that light signals not only convey messages but also help extend the lifespan of the lights. Flashing headlights to signal yielding shouldn't be too aggressive, as it can easily burn out the bulbs. Hazard lights are used for accidents or breakdowns, telling others to keep their distance. Proper use of turn signals allows pedestrians or vehicles to anticipate, preventing rear-end collisions. Abnormal flashing of brake lights indicates a system issue, signaling it's time for maintenance. When high beams are directed at each other, switch to low beams to avoid excessive glare that impairs visibility. These practices save the car and ensure safety.
