What does it mean when your blinker blinks too fast?

As pleasedodgevan2 noted, often it’s a faulty bulb, where the element has shorted to ground. If new bulbs don’t cure it, you’ll need to look deeper – starting first at rusted out bulb sockets. Usually, when the turn signals blink too quickly, a bulb is out. I would think that a short to ground would blow the fuse for the circuit.

What to do if your blinkers don’t work?

If the bulb in your signal dies, then it’s a pretty straightforward fix — simply replace it with a new one. Turn signal lights usually last a few years, but they can die quicker if you use them often. The turn signal switch is the device near your wheel which controls your signal. A faulty signal switch can’t send a signal to the blinkers to work.

Can a bad signal switch cause a blinker not to work?

A faulty signal switch can’t send a signal to the blinkers to work. Sometimes the problem may lie in the wiring, or in the switch itself. If the problem lies with the switch then it’s likely getting stuck in position due to the clock-spring. Regardless, the problem isn’t the blinker itself, but the device that communicates with it.

What happens if you lose a blinker bulb?

Losing one of the bulbs will NOT kill the other, like cut-rate Christmas lights. You’d still have the unaffected bulb/s working…this is an important safety consideration. AFAIK, modern turn signals have “logic” built into them, such that, if an unusually low current us drawn, they blink fast to alert the driver.

Why don’t my blinkers work?

If both rear turn signal lights are not working correctly, it’s most likely due to an electrical relay or fuse that supplies power to the tail lights. However, if it’s a fuse, it’s likely that the parking lights (when you turn on headlights) and/or hazard lights are also not working.

Why would a turn signal stop working?

Most experts will tell you that if your turn signal isn’t working, it’s because of one of two reasons. Either your bulb is burnt out, or you have a faulty turn signal relay. A turn signal bulb, like other broken lights or worn out bulbs, is easy to replace.

Why is your turn signal blinking fast?

The main reason why turn signals start blinking really fast is a bulb failure in the head lamp. When the bulb fails to work properly because it has been damaged or broken, the resistance switches adapt to the sudden change by making the light blink repeatedly in a very fast manner.

How do you troubleshoot turn signals?

Here are some steps you can take to troubleshoot the problem: First, check the bulb. Most likely, the turn signal bulb is a two-filament type. Examine the bulb socket for corrosion or damage. If necessary, check the socket ground and power connections.
