Electronics » Canbus and Denali B6

Just got the Denali B6 brake light from Nippy Normans, who on their website say it can be fitted with or without a Cansmart.

Fitted as per instructions, running light works fine, but as soon as I cut into the brake light cable, the TFT throws up a brake light warning error.

Some googling seems to show that this can't be fixed without buying a CanSmart Unit which I specifically didn't want to do at £200 extra just for the additional brake light.

Any advice? Is it possible to get it working without the CanSmart?

TIA

Oh that’s annoying, it will more than double your cost of installation if you need a Cansmart, I already had a Denali Cansmart fitted so for me it was a straight forward installation and very effective .
Sorry I don’t know if it can be fixed without a Cansmart.

Thank, doing some googling I'm starting to think it can't, I'll give NN the benefit of the doubt, but if it can't they should really put that on their webpage, as it goes from being a £99 instal to £318 🙄

Just to finish this thread off for anyone with a similar question, NN replied, you can only use this with an EzCan or Cansmart.

So the £99 item actual becomes £300.

Sounds like they should have better elaborated. To use it as a supplemental brake light (no CANSmart), you would need to power the light independently but triggered by the brake light. Otherwise you’re adding a bulb to a circuit and making the system thing something is wrong due to excessive draw.

I went with SkeeneLights which use a separate power feed to a control module and a signal wire that lets it know when the light is engaged. Any auxiliary light that does not have a control module will likely mess with CANbus systems.
