Why is the car's turn signal flashing very fast?
2 Answers
The main reasons why a car's turn signal flashes very fast are: 1. A burnt-out turn signal bulb. Generally, turn signal bulbs such as the turn signal, front fender light, cornering light, or rear turn signal - if any of these bulbs are burnt out, it may cause the flashing frequency to become too fast during turns. 2. Poor contact in the turn signal: such as loose bulbs or poor plug connections. 3. Faulty bulb control relay: The relay controlling the turn signal light system circuit may be the cause. 4. Lighting circuit faults: Multiple reasons including poor wiring connections, poor grounding, incorrect bulb installation, rust, etc.
I've encountered this issue with my car before - the turn signal suddenly starts blinking unusually fast, which usually indicates a burnt-out bulb. Don't underestimate this phenomenon; it's actually your car's electrical system sending you a message. When the current in the circuit becomes abnormal, the little box controlling the blinking frequency speeds up to alert you to check. From my DIY experience: first walk around the car to see which turn signal isn't working, then open the corresponding light cover to replace the bulb - you can buy one for just 10 yuan at auto parts stores. However, make sure the wattage matches on both sides, otherwise it'll blink fast again next time. Also, in some older cars, aging wiring can cause poor contact - in such cases, you'll need to sand the metal contacts with sandpaper.
