How To Replace Your Flasher Relay

Flasher relays are controllers for hazard signals and turning signals. One may be used on both turning and hazard signals. Other automobiles use two signal flash relay for each. It would be better to check if your vehicle is using two flasher relays. Flasher relays sizes roughly around 1"x1"x1.5”.

Flasher relays are found under the motorcycle’s seat or in the back of the headlight most of the time. In cars and vans, flasher relays are in different places, maybe below the dash or on top of the brake pedal. The placement may differ depending on the car manufacturer. Flasher relays need replacement when your signal is not blinking or when it does not come out. It is better to check the fuses sometimes. Blown fuses may be the cause why they aren’t functioning.

Replacing flasher relay requires plenty of tools. It requires electrical crimping pliers, ratchet and extensions. Some uses crimp-on connectors and electrical tapes. Soldering iron is an option if you want better wire connections.

If you are using a motorcycle, you can replace the flasher relay by following these steps:

  1. Locate the placement of the flasher relay. Most of the time it is under the motorcycle’s seat. It may also be positioned behind the headlight.
