General ezCAN FAQ's

The latest version of the HEX ezCAN User Manual can be found on our software page, under STEP 1: GETTING STARTED, which is just below the download links for Windows and MAC ezCAN configuration software. The manual’s cover page states the version (edition) of the manual, and in the footer of the pages you’ll see from which version of the software onward it is based on.

The HEX ezCAN unit is highly water resistant and dustproof. Blanking plugs are provided to protect unused outputs.
Your warranty is not voided because you do not cut, or tap into, any wires.
The warranty period of an ezCAN device is two years from the date of purchase. Note that the warranty is only valid if the device has been registered on our registration portal.

During the registration process it might be possible to submit the same registration request twice by clicking on the link in quick succession. The first email received will contain the confirmation link, but the second email contains the message that you are the previous owner. This can be ignored, and the link sent in the first email can be used to complete the registration.

Some email clients break the token up in two parts. Selecting the token as a hyperlink then fails, as only a part of the full token forms part of the URL. To fix this, rather copy the entire token and paste it in a text field, remove the empty space in between the two parts, and paste that in your browser.

For example: Ggtj4F3 H46vdf52Z needs to be: Ggtj4F3H46vdf52Z

  • 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor

For ezCAN units with 3-wire connectors:
  • Solid colour (red/orange/yellow/white) to Denali light’s red wire
  • Black to Denali light’s black wire
  • Dual colour wire (red/white or white/black) to Denali light’s yellow or white wire
For ezCAN units with 2-wire connectors (note that you may experience flicker at low-intensity settings):
  • Solid colour (red/orange/yellow/white) to Denali light’s red wire
  • Black to Denali light’s black wire
  • Leave Denali light’s yellow or white wire unconnected
  • There are multiple ways of connecting your Skene lights and IQ-260 controller to the ezCAN, depending on which features you want.
    • You can connect the P3 lights directly to the brake output of the ezCAN and leave the Skene brake light controller off the bike.
    • If you want the Skene controller features you can power the controller from the ezCAN accessory output and use the ezCAN brake output to drive the Skene controller’s brake input. Using the Skene instructions at https://www.skenelights.com/installation-p3, connect the wires and configure the ezCAN as follows:
      • ezCAN accessory output (white) to Skene Switched +12V (red)
      • ezCAN brake output (yellow) to Skene Brake Light (white)
      • ezCAN accessory or brake ground (black) to Skene Ground (black)
      • Configure the ezCAN to use channel configuration 1, 3 or 4 and set the tail/rear light brightness to 0% and the brake light brightness to 100%. Set the ezCAN brake to “No flashing”.
  • See the Skene FAQ for more options and information, www.skenelights.com/faq-1

There are multiple ways of connecting your Admore light to the ezCAN. To make full use of the features of the Admore light connect the wires and configure the ezCAN as follows:

  • ezCAN accessory output (white) to Admore Red (switched 12V source)
  • ezCAN brake output (yellow) to Admore Blue (brake input)
  • ezCAN accessory or brake ground (black) to Admore Black (ground)
  • Admore green and yellow (right/left turn signal inputs) can be tapped directly into the turn signal wires of the bike, as per the Admore instructions
  • Configure the ezCAN to use 2 channels with the yellow and white configured for brake and accessory respectively, remember to set the tail/rear light brightness to 0% and the brake light brightness to 100%. Set the ezCAN brake to “No flashing”.

Yes, it can. We have evaluated and tested a set of Clearwater Krista lights using an Accelerated Ageing Test which is equivalent to 7+ years worth of riding (see the details of our evaluation and test below). We believe that the Clearwater lights will work reliably with the HEX ezCAN.

Unfortunately we have been getting reports that Clearwater Lights has been telling their customers that their lights should not be used in conjunction with an ezCAN as it would seem to be working initially, but then eventually the ezCAN would cause their lights to fail.

Clearwater Lights, like many other high-end LED lights, use a LED controller chip made by Linear Technology (LT) that has an additional “brightness” control pin. Many other good quality LED lights use the same (or similar) controller chip but ignore the brightness pin on the controller chip. This is not out of spec and according to the datasheet of the controller, is a very real and valid implementation of the design. Further, the frequency of the internal current control loop is thousands of multiples higher than the frequency that the HEX ezCAN uses to PWM the power to the lights. That means that to the internal LED and LED controller chip this low frequency is as good as ignorable.

Why do LED lights fail?
Failure of electronic components is a reality. Assuming that the LEDs are supplied with the correct voltage and not over-driven, the two most common reasons for failure are the use of inferior components or an inferior design that unnecessarily stresses the electronic components to the point of eventual failure. Very typical are failures of the power capacitors that have to deal with the continuous inrush and ripple currents.

We have a set of Kristas and have evaluated the Clearwater Lights design. They manufacture very high quality lights which are well respected in the biking community and we saw no trace of the use of inferior components.

The opinion of a specialist
We contacted one of the LT Field Application Engineers and ran this by him, his response was: “I agree with you, there is no issue with these parts. They are designed to work in a switching environment and it does not matter how you switch them as long as the forward or reverse breakdown voltage ratings of them are not exceeded. They are diodes afterall so pretty resilient. There can be voltage spikes when switching, due to inductive parasitics etc which could overvoltage them but that’s an OV problem, not a susceptibility to switching problem.”

We designed a Test
What we did was to set up an Accelerated Ageing Test. The average mileage seems to be around 2500km/year. In order to work with a worst case scenario, we used 10,000km. Then we made an assumption of the speed that the rider averages over those 10,000km and we chose 60km/h. That means after 7 days of continuous use that would equate to the same ON-time of a bike that did 10,000km travelling at an average speed of 60km/h. Now leave them ON for 35 days and you have an accelerated test that equates to 5 years worth of “normal” use.

We hear you saying but I ride more or less than that and my average speed is X. Well, now that you know how we calculated it, just plug in your own numbers – if you drive only 5,000km in a year, then this test equates to you using your lights for 10 years!

Naturally you need to pay good attention to the conditions too. Like any good LED light, the Clearwater lights have temperature compensation. That means the lights will decrease their current draw in order to minimise the power dissipation. In order to create the worst case scenario test, we need to run the lights for the duration of the complete test and the maximum power dissipation. How do we do that? We set the ezCAN brightness to 90% (100% would not have any switching) and then we introduce just the right amount of airflow to keep the lights cooled to remain working at their maximum power level (and we monitor this at a at least twice daily during the test).

The Test results
The lights passed the 5-year Accelerated Ageing Test with flying colours! As a matter of fact, we left the test running, and at the time of this writing they were working perfectly after 1000+ continuous hours of being powered by the HEX ezCAN, which equates to over 7+ years in the Accelerated Ageing Test.

To conclude we have explained why technically the HEX ezCAN can be used with Clearwater Lights.

As most of you know, development on the ezCAN never stops. This is why we have an official beta testing program, allowing participating users access to developmental functions and features.

Due to the nature of beta software we don’t list the new features publically, so if you’re interested feel free to contact our support team to confirm what the latest beta features are.

Currently we have ezCAN’s for BMW and Harley Davidson motorcycles. We also started investigating ezCAN support on KTM recently.

We appreciate feedback from our customers, so if you have any new motorcycle brands in mind, let us know!

Here are the meanings of the different states of the LED on the ezCAN:

  • Constant green: The device is operating normally
  • Flashing green: The device is in sleep mode and will resume normal functionality when ignition is turned on
  • Constant red: Major fault on device. Device will attempt to recover when connected to ezCAN software. 
  • Flashing red: Possible circuit overload. Connect device to ezCAN software to see which circuit is affected
  • Flashing orange: Possible fault on unit. Connect device to ezCAN software to see exact fault

For a video on the above, refer to our Youtube channel.

The ezCAN acts as a relay and fuse for your accessories, and as such, you do not need to add or use any external fuses or relays that come included with some lights. Instead, connect the lights directly to the ezCAN. Controlling the lights’ on/off and brightness is listed under BMW FAQ as “How do I configure my lights while on the move.”

The nuisance threshold refers to the speed at which the ezCAN instructs the brake light to start flashing while riding. This is to prevent constant flashing while filtering or riding at low speeds.

The sensitivity setting/slider for emergency stops and engine braking is designed to allow you more control over when your brake light should communicate to other drivers/riders that you are decelerating hard by means of your configured flash setting.

You can follow the steps listed here as a temporary workaround:


Yes, we have implemented independent turn signal functionality in our software (only compatible with Gen II devices). Although this is specifically aimed at riders looking to hook up a trailer and take some longer journeys, you can also fit aftermarket turn signals and wire them up with the ezCAN. Do keep in mind that these take up a dedicated circuit each (two in total). We have a separate entry for Weiser’s 3-in-1 lights, please see below.

Yes, the lights however cannot be dimmed by the ezCAN as they flicker, so you’ll need to set the running light at 0% in the ezCAN software, along with the brake light at 100%. The three inputs that comes with the Weiser lights can be connected as below.

The 3-in-1 wire: this can be driven from the ezCAN through a brake output and then:
Turn : turn signal input, which needs to be directly tapped into the OEM turn signal input wire
Earth : ground/earth return, which is direct to the OEM turn signal return

The flashing features do work with the lights, but they could interfere with the turn signals when they are active. Inverse flashing with hazards (for front aux lights) should be turned off along with the “Off when turn signal active” feature. Modulation will naturally be turned off as well, as these functions do not correlate with the Weiser lights’ goal. Also remember to disable three wire dimming.

Although the brake light flashing should work as expected, they could also interfere with the turn signals, so we’d suggest maintaining “No flashing” as the setting on the brake light.

Not at all, the maximum draw of those blips is 800μA (microamps)/hour. In order to completely drain a 12V battery, the ezCAN would need to be connected to it for more than a year.

Yes, we have worked with many of our clients to get the best way of controlling your heated gear through the ezCAN. You will need to setup the gear as a set of auxiliary lights in the your software, this will allow you to alter the intensity on the move. Keep in mind that the heated gear will require that all aux light functions are disabled, such as strobe on horn, strobe on flash to pass and flash on turn signal active, as this will not provide constant 12V to the gear. Changing the intensity on the move can be controlled with the Multi controller (as if you are increasing/decreasing brightness) and the channel the heated gear is connected to can be turned off with the turn signal cancel button. The same can be achieved on the oil cooled R1200’s and F-series bikes using their info button as described here (https://www.hexezcan.com/software/) under step 4.

Yes, you are welcome to disconnect the OEM horn, but this will result in a fault code on your bike.

Not yet, we are always looking to add more makes of bikes, but this process takes a lot of time and research to develop and implement. Please contact us with any relevant details of your bike, i.e. wiring diagrams/photos of diagnostic connectors/etc.

Click here to review our software page. Under step 4, you will find how to adjust your auxiliary lights brightness and turn them on/off while on the move.

The main difference between the two devices are the output circuits. The Gen II devices offers 4x 10A outputs instead of the 2x 10A and 2x 4A on the Gen I, so you can connect higher output accessories to the device.

The other difference is support for two sets of individually operated lights. This allows users to change the intensity of each pair lights individually, or even turn a pair off or on while on the move.

If you have any questions feel free to contact our support team

We have had a few clients who have done this in the past. The connector to the bike will need to be replaced by one of the ezCAN connectors, you should only require the striped red/blue wire and brown. You can view the connector below:
