Why Is My Turn Signal Blinking Fast?

Do you notice a turn signal blinking fast on your vehicle? A fast-blinking turn signal may indicate a few different issues with your vehicle, which we will outline here. In general, a turn signal blinks fast when there is a problem with the electrical system of your vehicle. In newer, LED-based lighting, there is less of a chance of a fast-blinking turn signal due to the lower electrical requirements from LEDs and because LEDs don’t burn out as quickly.

Why Is My Turn Signal Blinking Fast When I Activate It?

There are a few main reasons why your turn signal is blinking fast. The most common reason why a turn signal blinks fast is due to an interrupted electrical circuit. A turn signal needs to blink at the right speed when the circuit is complete from the battery to your dashboard to the turn signal at the front of your vehicle. 

Due to the circuits in your vehicle, a turn signal needs precise amounts of current, resistance, and voltage to operate. If any of these change, you might see a turn signal blinking fast. It’s usually a minor issue that needs correcting. See the four common causes for a turn signal blinking fast on drives around Lincoln and beyond:

• The bulb needs to be replaced
• Bad ground connection
• Weak voltage
• Loose or damaged connections 

Why Is My Turn Signal Blinking Fast With an LED Bulb?

The answer here is that you’ve probably retrofitted an incandescent lightbulb with LED lights on an older car that didn’t originally have them. When a fast-blinking turn signal happens in this scenario, it’s called hyper-flashing. The cause is a lack of compatibility between the LED lights and the analog systems of older cars. 

You can solve this problem with these remedies:

• Fitting a new turn signal relay, or replacing an existing relay. 
• Installing load resistors that copy the original load demand. 
• Choosing LEDs with a decoder and resistor already built in.
