Description
The problem with traditional T3 setups… solved
The original Denali T3 has been one of the most popular multifunction lighting upgrades on the market — combining run, brake and turn signals into a compact, powerful unit.
But there’s always been one challenge…
They require multiple circuits to function properly.
A full front and rear T3 setup can use up to four circuits on your ezCAN or CANsmart — and that quickly becomes a limitation when you’re also running auxiliary lights, a SoundBomb horn and rear lighting like the B6.
That’s where the T3-S changes everything.
The new Denali T3-S Smart pods connect via the ezBUS (white circuit) on HEX ezCAN systems, delivering full run, brake and turn signal functionality using just a single channel.
No more sacrificing circuits.
No more compromises on your setup.
No more needing a second controller.
Key Features
- Red rear running lights (DRL)
- Brake light functionality (increased intensity under braking)
- Integrated turn signals (amber override left/right)
- Smart ezBUS integration (1 circuit only)
- Optional smart features including programmable flash patterns
- Additional visibility modes (including fog light-style flashing – configurable)
T3 vs T3-S — What’s changed?
Denali T3
Circuits required:
3 circuits for a rear pair
Run / Brake / Turn:
Yes
Wiring:
More complex
Smart features:
Limited
Best for:
Traditional ezCAN / CANsmart setups where enough circuits are available.
Denali T3-S Smart
Circuits required:
1 ezBUS circuit
Run / Brake / Turn:
Yes
Wiring:
Simplified smart connection
Smart features:
Enhanced ezBUS features
Best for:
Modern smart ezCAN setups where you want full T3 functionality without using multiple channels.
Why this matters
A typical setup might include:
- Front auxiliary light pods (2 circuits)
- SoundBomb horn (1 circuit)
- B6 rear brake light (1 circuit)
- T3 rear lights (3 circuits)
That’s 7 circuits total — meaning you’d normally need two controllers.
With T3-S, that drops dramatically.
The rear T3-S now uses just one circuit, freeing up capacity and often removing the need for a second ezCAN entirely.
Compatibility
The Denali T3-S Smart pods are designed to work with HEX ezCAN systems using the ezBUS (white circuit).
Compatibility with other controllers such as Denali CANsmart may vary depending on firmware and support for smart accessories.
If you’re unsure whether these will work with your current setup, contact us before ordering and we’ll advise.
Installation
We offer professional installation at A Bike Thing HQ and through our approved UK installation partner network.
Due to the simplified wiring of the T3-S system, installation is significantly quicker and cleaner compared to traditional T3 setups.
The original T3s were brilliant — but they came at the cost of circuit usage.
The T3-S keeps everything that made them great and removes the biggest limitation.
If you’ve ever held back on T3s because of wiring complexity or circuit limits — this is the upgrade you’ve been waiting for.
