ELFR-1 Electronic LED Flasher Relay with OEM Connector

Now you can finally fix the flash rate on your motorcycle with our unique Plug And Play solution!  That's right, our Electronic LED Flasher relay directly replaces the stock flasher relay on many Yamaha, Honda, Kawasaki, Suzuki, KTM, Triumph, and other motorcycles by plugging directly into the harness in place of the OEM flasher relay.

Whether your OEM relay has 2-wires or 3-wires, our flasher relay is a direct replacement for compatible motorcycles when the 3rd wire is simply a ground connection, which our relay does not require. Use our Motorcycle LED Flasher Relay Compatibility Guide to confirm whether the ELFR-1 is the correct Custom LED relay for your motorcycle.

For motorcycles with nonstandard two wire flasher relays, this flasher relay can still be used by removing the connector and hard-wiring it. Even three wire flasher relays can be replaced if one of the wires is a ground wire. We also have a connector option on our ELFR-1-QD model, which may be more useful for hard-wire and custom applications.

This unit is guaranteed to replace any two-wire flasher relay and operate at the normal DOT blink rate for motorcycles with stock blinkers, LED blinkers, or any combination of both, provided the total load on the system is within 0.05A to 10A (0.6 Watts to 120 Watts!) - which basically covers the majority of blinker products on the market.

See the Installation Tab for more important details.

Your motorcycle must have a rectified standard 12VDC system for this flasher relay to work (most bikes are 12VDC).

• Minimum Rated Current: 0.05A
• Maximum Rated Current: 10A
• Rated Voltage: 12VDC
• Flash Rate: Constant
• Size: 1.2" x 1.77" x 0.74"

ELFR-1 Compatibility

Use our Motorcycle LED Flasher Relay Compatibility Guide to confirm the correct Custom LED relay before ordering. The guide includes compatible motorcycles, recommended Custom LED relay model, OEM relay part numbers or relay body markings when available, and important fitment notes.

Important: This guide is intended for U.S.-spec applications unless otherwise noted. Non-U.S. models, previous owner wiring changes, and mid-year production changes may differ. When in doubt, compare your motorcycle's original flasher relay connector before ordering.

If your motorcycle is not listed, the ELFR-1 may still work as a hard-wire replacement for many two-wire flasher relay systems, or three-wire systems where the third wire is only a ground. See the Installation tab for general hard-wire guidance.

The Custom LED ELFR-1 Plug-And-Play Electronic LED Flasher Relay comes with detailed installation instructions.

Installation of this product requires that you identify and replace the OEM flasher relay on the motorcycle.  If you are unfamiliar with the location of your OEM flasher relay, or electronics in general, please consult a qualified technician or your repair manual for additional information.

Installation of the ELFR-1 is as follows:

General hard-wire installation guidance

NOTE: You may lose your self-canceling feature by replacing the flasher relay if your bike is equipped from the factory with self-canceling turn signals. If you want to keep this feature, use our Stage II Load Equalizers instead.

If your existing flasher relay is a two wire flasher relay (or a three wire with a ground wire), and you have access to it, you can replace it with our flasher relay.

Identify and connect the wires leading to the OEM flasher relay as follows:

• Red wire on ELFR-1 to power source (ignition switched +12v)
• Black wire on ELFR-1 to load (blinker lamps / blinker switch)
• If the factory connector has a ground wire, leave it unconnected.

If you find that your motorcycle's flasher relay is not two-wire and/or replaceable, you may use the Custom LED Universal Load Equalizers along with your stock flasher relay instead.

NOTE: In some rare instances, when there are NO incandescent loads on the blinker system (LEDs front and rear), additional actions or components may also be required to prevent a wide range of blinker problems. These problems are all associated with a lack of resistive load on an all-LED blinker system that was designed for incandescent lamps. Problems such as, but not limited to: the 4-way blink problem (both sides blinking at the same time), the no-blink problem, and Integrated LED Tail Lights staying in "blinker mode" due to non-zero blinker voltages. Rest assured that Custom LED has the knowledge, experience, and expertise to tackle any issues that may arise on your motorcycle.

Remember, the Flasher Relay ONLY controls the speed of the blinkers on the motorcycle, and any other problems that arise are independent of the flasher relay, and are resolved separately as well.
