What Causes the Faster Blinking Speed of Car Turn Signals?
2 Answers
Car turn signals blink faster for the following reasons: 1. Burned-out right turn signal (same side): Typically, if any bulb in the right turn signal system—such as the right front turn signal, right front fender light, cornering light, or right rear turn signal—is burned out, it may cause the turn signal to blink too quickly. 2. Poor contact in the right turn signal: Issues like loose bulbs or poorly connected plugs can lead to this problem. 3. Inconsistent power or model of the right turn signal bulb: Some car owners may replace turn signal bulbs with non-standard models or bulbs of incorrect wattage (either too high or too low), resulting in faster blinking.
I've encountered the issue of the turn signal blinking unusually fast while driving before, which is usually caused by a burnt-out bulb on one side. Cars are designed with a safety mechanism where the flasher relay automatically increases the blinking speed as a warning signal when there's a bulb failure due to changes in resistance. I've checked it myself a few times and found that if the right turn signal blinks fast, it's the right bulb that's faulty, and the same goes for the left side. This is a pretty common issue, especially in older cars, as bulbs tend to fail when they reach the end of their lifespan. I recommend replacing the faulty bulb first—it's inexpensive and something you can do yourself. If the signal still blinks fast after replacing the bulb, it might be due to poor circuit contact or a faulty relay, in which case you should have a professional check the wiring and voltage. Don't ignore it, as it could lead to accidents when turning since others won't be able to see your turning intentions—safety first!
