Installing a 12V flasher relay can be a daunting task, especially for those who are new to wiring diagrams. Fortunately, this guide will provide you with all the information you need to successfully wire a 12V flasher relay. From the basics of wiring, to frequently asked questions, this guide has you covered.
What is a 12V Flasher Relay?
A 12V flasher relay is a device that controls the speed at which a set of light bulbs blink, or “flash”. This device is commonly used in the automotive industry to control the blinker lights on a car or truck. The 12V flasher relay operates by intermittently interrupting the current flow to the light bulbs, causing them to blink on and off at a regular interval.
How Does a 12V Flasher Relay Work?
The 12V flasher relay is made up of several components, including a power source, a switch, a load, and a time delay circuit. When the switch is closed, the power flows through the time delay circuit, which causes the relay to open and close at a regular interval. This, in turn, causes the load (in this case, the light bulbs) to flash on and off.
The frequency of the blinking is determined by the time delay circuit, which can be adjusted to achieve different blinking rates. The time delay circuit typically consists of a capacitor and a resistor, which work together to control how quickly the relay opens and closes.
How to Wire a 12V Flasher Relay
Wiring a 12V flasher relay is a relatively simple process, but it does require some basic knowledge of electrical wiring. Follow these steps to successfully wire your 12V flasher relay:
- Locate the power source for your blinker lights. This will typically be the battery or fuse box.
- Connect the positive wire of the blinker lights to the “load” terminal of the flasher relay.
- Connect the negative wire of the blinker lights to a ground source.
- Connect the positive wire of the power source to the “power” terminal of the flasher relay.
- Connect the negative wire of the power source to a ground source.
- Adjust the time delay circuit to achieve the desired frequency for your blinker lights.
Once you have completed these steps, your 12V flasher relay should be properly wired and ready to use.

FAQs
What is the purpose of a 12V flasher relay?
The purpose of a 12V flasher relay is to control the speed at which a set of light bulbs blink or flash. This device is commonly used in automotive applications to control the blinker lights on a car or truck.
How do I adjust the frequency of my blinker lights?
To adjust the frequency of your blinker lights, you will need to adjust the time delay circuit of your 12V flasher relay. This can typically be done using a small screwdriver or other tool to turn the adjusting screw on the time delay circuit.
Can I use a 12V flasher relay with LED lights?
Yes, a 12V flasher relay can be used with LED lights. However, you will need to make sure that the relay is designed to work with LED lights, as some relays are only designed to work with incandescent bulbs.
What happens if my 12V flasher relay fails?
If your 12V flasher relay fails, your blinker lights will either stop working altogether, or they will begin blinking at an erratic rate. In either case, you will need to replace the flasher relay to restore normal operation of your blinker lights.
Can I install a 12V flasher relay myself?
Yes, you can install a 12V flasher relay yourself if you have a basic understanding of electrical wiring. However, if you are unsure about how to properly wire the flasher relay, it is recommended that you seek assistance from a qualified professional.
Conclusion
Wiring a 12V flasher relay can be a tricky task, but with the right knowledge, it is a task that can be completed successfully. By following the steps outlined in this guide, you can wire your 12V flasher relay with confidence, knowing that you have the information you need to get the job done right.
