All about LED Load Equalizers for LED Blinkers on Motorcycles

You may have heard the term "Load Equalizer" or "Load Resistor" being thrown around when looking for a solution to your fast-blink or no-blink issues on your motorcycle.  The fast blink issue occurs when you remove the OEM incandescent blinker lamps and replace them with LEDs.  

Well, understanding what a Load Equalizer is, starts by understanding why you need one in the first place.

Why do I need a Load Equalizer?

If you remove any of the OEM blinker lamps on a car, truck or motorcycle, you may find that your blinkers now blink faster than they did originally - or they stop blinking entirely!  The Fast-Blink rate is actually the designed response of the OEM flasher relay.  It's designed to blink fast when the Flasher Relay detects that a light bulb is burned out.  This way, the operator knows he has a light bulb that needs to be replaced.  

The Flasher Relay makes this burned-out-bulb determination by checking the amount of current being drawn through the Flasher Relay to power the blinker lamps.  When using LEDs blinker lamps, there is FAR less current being drawn on the blinker circuits compared to the OEM incandescent bulbs.  It is because the LEDs are so efficient that they draw such little power.

What the heck is a Load Equalizer? 

A Load Equalizer is used as a power-sink, to dissipate the same amount of power as the OEM turn signal lamps did.  

This means, if you had 25 Watt light bulbs originally on your turn signal circuit, you need to add 25 Watts worth of Load Equalization to create the same power draw on the blinker circuit as with the OEM lamps installed.

If you match the power draw properly, your Flasher Relay is tricked into thinking the bulbs are still there!  And like magic, it starts blinking normally again!

Where do I get the Correct Load Equalizer for my application?

What you need to do is find out the wattage of the OEM blinker lamps that you have removed or replaced with LEDs.  You will need to add this amount Wattage with Load Equalizers.

Custom LED makes the finest Load Equalizers for motorcycle applications.  They do not get dangerously hot like some other cheaper alternatives out there, and we have been making them since 2001!  Tried and true is the way to go.

What about replacing my Flasher Relay instead?

YES!  Replacing your Flasher is the best way to fix fast-blink or no-blink issues.  If we have an LED Flasher Relay that will work for your application, then forget about Load Equalizers.

By changing the OEM Flasher Relay to one that does not have a bulb-out notification, and is designed to work with very low current draw, you are taking advantage of the power-saving aspects of LED blinkers!  

Why put the large electrical load of the incandescent lamps back on your blinker system just to trick the OEM Flasher Relay, when you can just replace the OEM Flasher Relay with an Electronic LED Flasher Relay that blinks normal regardless of what blinker lamps you are using?

Custom LED makes a few different types of Electronic LED Flasher Relays for Motorcycles.  See which one is compatible with your bike on the respective product pages.

CBR 600RR Flasher Relay Replacement for LED, Years 2003, 2004, 2005, 2006

So, you may be wondering where the flasher relay is on your 2003-2006 Honda CBR 600RR.  You have changed your OEM blinker lamps to LEDs and/or installed our 2003-2006 CBR 600RR Blaster-X Tail Light on the rear, and now the blinkers blink fast, or don’t blink at all.  You know you need to replace the flasher relay, but nobody seems to have one compatible with your bike!

Worry not, Custom LED has the answer, and the solution!

The flasher relay on your bike is physically built into the gauge cluster.  “Replacing” it requires disconnecting two particular wires leading to the gauge cluster, and connecting the Custom LED ELFR-1 LED Flasher Relay to these wires.  We do not provide a step-by-step technical how-to for this installation because there are many 600RR versions, however there are many DIY write-ups on the internet about this exact installation.

A very useful and informative 2003-2006 CBR 600RR ELFR-1 Flasher Relay Install YouTube video clearly shows an approach that does not require any wires to be cut!

From the information we have gathered, there are two wires leading to the gauge cluster you need to identify for a proper installation of our ELFR-1.

  • Gray wire (blinks +12V with the blinkers on, this is your Load wire coming from the stock relay)
  • White/Green stripe (ignition switched +12V)

You must check these wire functions yourself with a volt-meter or test light before proceeding.  OEM Manufacturers can change wire colors slightly from year to year, and region to region.

  • The Gray wire gets attached to the BLACK wire on the ELFR-1 (attach to the wire going away from the gauge cluster, not to the gauge cluster)
  • The White/Green stripe connects to the RED wire on the ELFR-1 (attach to the wire going away from the gauge cluster, not to the gauge cluster)

NOTE: It is critical that you effectively disconnect these wires from the gauge cluster, otherwise the OEM relay will still control the blinkers and cause the malfunction you are experiencing to continue.

The Hard-Wire installation is somewhat tricky if you are not familiar with electronics, and for this reason we generally recommend load equalizers for the 2003-2006 CBR 600RR instead.
