If you’re looking for one of the most effective rear-visibility upgrades you can make to your motorcycle, pairing LED rear turn signals with the re-designed SMART Triple Play module from Custom Dynamics is hard to beat. This setup transforms basic rear lighting into a fully functional run-brake-turn system with customizable flash patterns and brightness control. You get all this in a compact, plug-and-play package that fits neatly under your seat.
Let’s take a look at how the updated SMART Triple Play works, what makes it different, and why so many riders are gravitating towards it when installing rear LED turn signals.
What the SMART Triple Play Module Does
The redesigned SMART Triple Play is now smaller and sleeker, making under-seat installation easier while keeping all of its advanced lighting logic. It converts rear turn signals on bikes with a center taillight into triple-function lights that include: running lights, full-power brake lights, and turn signals.
And even if you’re not upgrading to LEDs, the module works with both incandescent bulbs and LED turn signals. Once installed inline with your rear lighting harness, it instantly adds multi-function capability without cutting or splicing factory wiring.
For riders upgrading to LED rear signals, this module unlocks the full benefit of brighter output and faster response while adding programmable safety features.
Built-in Strobe and Flash Pattern Control
The SMART Triple Play includes ten user-selectable brake strobe and flash patterns, plus a steady brake option if you prefer a clean, non-flashing signal. Programming is handled with onboard switches and a rotary dial, with no need for an external programmer.
You can also choose exactly where the strobe or flash behavior appears:
- Center taillight only
- Rear turn signals only
- Both center and rear turn signals
- No strobe or flash
This flexibility lets you tune the system for your preferred mix of visibility and style.
Adjustable Running Light Brightness
Another great feature available is the ability to adjust running light intensity for the rear turn signals. Using the rotary dial programming mode, you can match the running brightness of the rear turn signals to your center taillight for a balanced, factory-like appearance.
You can also disable the running light function entirely and run the rear signals as brake-and-turn only if desired.
SMART Signal Override Logic
The built-in SMART function maintains proper signaling behavior when braking and turning at the same time. When both are active, the turn signal flash overrides the brake flash on the signaling side. That keeps your intentions clear to drivers behind you and maintains compliance with standard lighting logic.
For DOT compliance, rear turn signals must be red or amber. The module is compatible with red LED rear turn signals or stock bulbs paired with red lenses.
Expansion Capability
With the optional extension harness, the SMART Triple Play can control up to three dual-intensity lighting products as run-brake-turn outputs. That makes it a strong foundation for more advanced rear lighting builds using multiple LED elements.
Installation Overview
Installation is designed to be straightforward for most riders with basic tools.
General process:
- Disconnect the negative battery cable
- Locate and unplug the rear lighting connector at the rear fender
- Plug the SMART Triple Play inline between the rear harness and bike harness
- Reconnect the battery
- Secure the module under the seat with access to the rotary dial
- Program brightness and flash settings
- Test all lighting functions
Who This Upgrade Is For
This combo is ideal for riders who want:
- Greater rear visibility in traffic
- Multi-function rear lighting
- Customizable brake flash behavior
- Plug-and-play installation
- A cleaner, more modern LED lighting look
It’s a small module that delivers a big functional upgrade, especially when combined with quality LED rear turn signals.

Write-up says rear turn signals must be red. which is incorrect (or only partially correct) as they can also be Amber:
Rear Turn Signal Color Requirements – Federal Regulations
Rear Turn Signals: According to federal regulations, rear turn signals can be either red or amber. However, most vehicles in North America predominantly use red lights for rear turn signals.
Safety Studies: Research indicates that amber turn signals may reduce accidents more effectively than red ones. Studies have shown that vehicles with amber rear turn signals are less likely to be involved in rear-end collisions.
