Why is my indicator flashing fast then normal?
As a car owner, you may have experienced the perplexing situation where your turn signal indicator starts flashing rapidly before returning to a normal pace. This behavior can be concerning, but understanding the underlying causes can help you address the issue effectively. In this article, we will explore the reasons behind this phenomenon and what steps you can take to resolve it.
Common Causes of Fast Flashing Indicators
When your turn signal indicator flashes rapidly, it typically indicates a problem within the signaling system. Here are some common reasons for this behavior:
- Burnt-Out Bulb: One of the most frequent causes of fast flashing is a burnt-out turn signal bulb. The vehicle's electrical system compensates for the loss of resistance by increasing the flash rate.
- Faulty Wiring: Damaged or corroded wiring can disrupt the electrical flow, leading to irregular flashing patterns.
- Bad Relay: The turn signal relay controls the flashing of the indicators. If it malfunctions, it can cause erratic flashing.
- Incorrect Bulb Type: Using a bulb that does not match the specifications for your vehicle can also result in abnormal flashing rates.
Identifying the cause of the fast flashing indicator is crucial for ensuring your vehicle's signaling system operates correctly. If you suspect a burnt-out bulb, it's a good idea to check and replace it first.
Steps to Diagnose and Fix the Issue
If you're experiencing fast flashing indicators, follow these steps to diagnose and potentially fix the problem:
- Inspect the Bulbs: Start by checking all turn signal bulbs for any signs of burnout. Replace any faulty bulbs with the correct type.
- Check the Wiring: Look for any visible damage or corrosion in the wiring connected to the turn signals. Repair or replace any damaged sections.
- Test the Relay: Locate the turn signal relay in your vehicle's fuse box and test it. If it's faulty, replace it with a new one.
- Consult a Professional: If the issue persists after checking the bulbs, wiring, and relay, it may be time to consult a professional mechanic for a thorough diagnosis.
By following these steps, you can effectively troubleshoot the issue with your turn signal indicators. Regular maintenance and prompt attention to warning signs can help prevent more significant problems down the road.
Conclusion
Fast flashing indicators can be a minor annoyance or a sign of a more significant issue within your vehicle's electrical system. By understanding the common causes and taking the appropriate steps to diagnose and fix the problem, you can ensure your vehicle remains safe and reliable on the road. If you're ever in doubt, don't hesitate to reach out to a trusted auto service provider for assistance.

Why is my blinker blinking faster than normal?
The Bulb Is Burnt-Out
One of the biggest causes of a faster-than-usual turn signal might be a burned-out lightbulb for that side. A burned-out lightbulb could be an essential cog of an annoyingly fast blinking turn signal that doesn't stop since the bulb is sending an irregular current in the indicator system.
How much does it cost to fix a fast blinking turn signal?
The average cost for a Signal Flasher Replacement is between $131 and $143. Labor costs are estimated between $45 and $57 while parts are typically priced around $86. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.

How do I know if my turn signal relay is bad?
Turn Signals Don't Work
This is the most common symptom of a faulty turn signal relay. Once the relay is broken, the lights won't turn on with the switch. On some vehicles, the hazard lights also rely on the turn signal relay, so those lights might also cease to function.
Do all car blinkers blink at the same rate?
In simple terms, your indicators must flash at least once per second, up to exactly twice per second, but no faster nor slower. This means that the flash rate will entirely depend on the manufacturer and some cars may be up to twice as fast as other vehicles.
How do I fix an indicator flashing too fast?
If the dashboard indicator light is flashing faster than usual, something isn't right. In most cases, it's simply that one of the bulbs has blown and needs to be replaced.
What are the symptoms of a bad turn signal switch?
Common symptoms of a bad turn signal switch include:
- Turn signal lamps don't work at all.
- Only one side of the turn signal lights is working.
- Other car systems don't function properly or at all.
Why do blinkers blink at different speeds?
Factors like temperature, differences in resistance of the wires and the blinking relay, age of the car, moisture in the air, and manufacturing tolerances change the blink rate - not to mention there's no specific blink rate that car manufacturers have to live by.
How can you tell if a relay has gone bad?
Listen for an audible click as the electromagnetic coil activates and the internal switch closes. Switch your multimeter to continuity mode, listen for the audible beep, and test for continuity between the switch pins. If there's no beep, it means the switch pins are stuck open and your relay is faulty.
