By | April 12, 2022



If you are new to working with electrical systems, hazard 3 pin flashers or relays can be daunting. These wiring diagrams provide a helpful guide to how to wire a hazard relay, getting you up and running in no time.

A hazard relay is an important component of any electrical system and can be used to control multiple lights at once. When the hazard switch is activated, the relay will trigger the system to light the corresponding bulbs. It is useful for guiding visitors along a path or indicating that a vehicle has stopped, as used in emergency vehicles.

The wiring diagram will tell you what wires connect where and allows you to identify the live, neutral, and earth wires. To begin the wiring, first connect the live wire from the power supply to terminal one on the relay. Terminal two is connected to the lamp holder and this will then link to the neutral wire. Finally, connect the earth wire to the terminal three in the flasher relay.

Once all the wiring is complete, you can test the system by activating the hazard switch. If the wiring has been carried out correctly, the hazard lights will flash on and off at regular intervals.

It is important to note that if the wiring has not been done properly, it can lead to an unsafe electrical system and can result in damage to the appliance or injury to anyone who touches the appliance. It is therefore paramount that the wiring is conducted correctly and to ensure this, a qualified electrician should inspect the installation.

Hazard 3 pin relays can be a useful addition to your electrical system, offering increased safety and convenience. By following a wiring diagram, you can easily complete the installation yourself and enjoy safe and effective use of your hazard relay.
