Blinker Blinking Fast

Reasons for fast Blinking

If you are wondering “why is my left blinker blinking fast?” or “why is my right blinker blinking fast?”, we have answers to both of these questions below. Fast blinking can be caused by several factors, including:

Failed light bulb

Fast blinking usually occurs when a bulb in the circuit fails. When the bulb fails, it draws too much current, causing the other bulbs to draw more current. As a result of this surge in current, the other bulbs heat up and expand, causing them to come into contact with the metal socket.

A short circuit occurs when electricity flows through the metal socket. This short circuit blows a fuse or trips a breaker, shutting off power to the entire circuit.

Broken signal wiring

Whenever your turn signal blinks a lot faster than usual while driving, it’s usually an indication that there is something wrong with the wiring. As time goes on, the insulation on the wires can degrade, leaving them vulnerable.

In this case, the turn signals may blink faster as a result of a short circuit. The turn signal may stop working if the wire breaks completely.

Rusted relay

There is also a possibility that the relay that controls the blinkers is damaged or rusted. Rusting can cause the contacts to become corroded, which can cause them to stick together. This can cause the relay to stay on all the time or turn on and off erratically. Blinking lights are one symptom of a rusted relay.

There is an easy fix for a burned-out blinker bulb, changing the bulb. First, you’ll need to find a replacement bulb. They can be found at most auto parts stores, and they’re usually pretty cheap. Once you have the new bulb, remove the old one and insert the new one in its place. Then, screw the new bulb in, and you should be good to go!

Inspecting the light wiring

If your turn signal is blinking too fast, it’s usually an indication of a problem with the wiring. The first step is to check all the connections and make sure that they are tight. If they are loose, tighten them up and see if that solves the problem. If not, you will need to inspect the wire itself for damage.

Look for any cracks, breaks, or bare spots. If you find any, you will need to replace the wire section. Once you have repaired or replaced the damaged wire, your turn signal should be normal.

Check the relay

The relay is responsible for controlling the headlight’s current, so if it’s not working correctly, the headlights will blink too fast. To check the relay, first, locate it in the fuse box. Once you’ve found it check if it is rusted, then the relay needs to be replaced. You can usually find replacement relays at your local auto parts store.

What are the consequences of not fixing a fast-blinking blinker?

Ignoring a blinking blinker can have serious consequences. Not only can it lead to confusing other drivers, but it can also get you pulled over. In some states, it’s illegal to drive with a blinking blinker, so make sure to take care of the issue as soon as possible. It’s an easy fix, so there’s no excuse.

The Bottom Line
