What Causes a Car's Turn Signal to Flash Rapidly?

[McAlivia]

The reasons for a car's turn signal flashing rapidly are: 1. Damaged flasher relay; 2. Poor bulb contact; 3. Broken bulb filament; 4. Bulb with excessive power. Turn signals are important indicator lights that are activated when a motor vehicle turns to alert surrounding vehicles and pedestrians. The turn signal tube uses xenon tubes, controlled by a microcontroller circuit, working continuously with alternating left-right flashes. Situations requiring turn signal use: 1. When making left or right turns; 2. At a distance of 30 to 100 meters from an intersection, turn signals should be activated according to the turning direction; 3. When changing lanes without obstructing normal traffic in other lanes, the corresponding turn signal should be activated beforehand before changing lanes; 4. Turn signals should be activated when overtaking; 5. Correct use of turn signals is required when making U-turns, entering or exiting roundabouts, and starting or stopping.
