Custom LED currently has two Electronic Flasher Relays which are designed to blink at a preset flash rate regardless of what types of blinker lamps/LEDs are used. With nearly a zero minimum load requirement of 0.05A, these flasher relays will operate properly under conditions that the the OEM flasher relay will blink fast, or will not blink at all. Read more about each product below.
The ELFR-1 is a plug and play replacement flasher relay that operates at the standard DOT (stock) blink rate for motorcycles with stock blinkers, or all LED blinkers or any combination of both.
The ELFR-P is a programmable plug and play replacement flasher relay that has 10 pre-programmed user selectable flash patterns! The patterns are easily selected VIA a rotary switch on the flasher relay.
If you have been linked here and/or do not understand why you would need to replace your flasher relay when installing LEDs as turn signals, please read our FAQ.

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 most Yamaha, Honda and Kawasaki motorcycles by plugging directly into the harness in place of the OEM flasher relay! See the compatibility list.
For motorcycles with nonstandard two wire flasher relays (not on compatibility list), 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.
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!
NOTE: In some rare instances, when there are NO incandescent loads on the blinker system (LEDs front and rear), one pair of our Stage I Load Equalizers will 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.

This list will determine if your motorcycle harness is known to be Plug-And-Play with our ELFR-1 Flasher Relay! If your bike is not on the list, it may or may not be plug-and-play, and it is most likely still compatible as a hard-wired replacement for your OEM flasher relay. See hard wire instructions below for more information.

General Compatibility Note: Although we try to keep this Plug-And-Play list current and complete, there are many more bikes out there that are Plug-and-Play compatible, and hard wire compatible with our LED Flasher Relay. We can not list them all! If your motorcycle has a two wire flasher relay, our relay will work for certain but may need to be hard wired into the harness. For three wire flasher relays, if one of the three wires is merely a ground wire, our relay will work but may need to be hard wired into the harness.
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 as follows:
Yamaha: Roadstar line (some models), V-Star - hard wire installation as follows when replacing OEM relay with our Electronic LED Flasher Relay:
Suzuki: All late model GSXR's with two-wire replaceable flasher relays are also compatible, but require a hard-wire installation as follows:
Ducati: 996 - hard wire installation as follows when replacing OEM relay with our Electronic LED Flasher Relay:
All Applications: 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 as follows:
If you find that your motorcycles 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.
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 remove the OEM flasher relay 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:

Introducing the Custom LED ELFR-P Programmable Electronic Flasher Relay! This micro controller based, plug and play flasher relay has 10 preprogrammed user selectable flash patterns! The flash pattern is easily selected by a 10 position rotary switch conveniently located on the compact unit.
This flasher relay system will operate properly and consistently for blinker loads ranging from 0.1A to 5A, which basically covers any combination of any blinker products on the market!
The fuse protected 18" long harness allows for plug and play* operation for motorcycles listed in our compatibility list below. For motorcycles not on the list, the unit may be hard wired to any motorcycle with a two wire flasher relay, or three wire flasher relay system where the third wire is a ground. The extra long harness length, and compact overall size (2.36" X 1.68" X .67") allows for convenient mounting of the flasher relay, for easy access during flash pattern selection.
* in addition to the direct plug and play connector, a single ground wire with affixed loop connector must be connected to a common ground point - such as the frame or battery negative terminal.
Each flash pattern was optimized for effectiveness when used with ANY type of blinker indicators such as: LED blinkers, stock blinkers, incandescent blinkers or integrated LED tail lights! There are several different flash patterns ranging from DOT (stock) blink patterns to super intense strobing patterns to slow fading patterns. You can be sure to find a pattern that suits your taste!
NOTE: In some rare instances, when there are NO incandescent loads on the blinker system (LEDs front and rear), one pair of our Stage I Load Equalizers will 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.
