If you’re a Harley-Davidson® enthusiast looking to upgrade or replace your factory Turn Signal Module (TSM) or Turn Signal Security Module (TSSM), then Custom Dynamics has the perfect solution for you. Their new SMART TSM replacement is not only easy to install but also reliable and fully compatible with Harley models from the early 2000s. Moreover, it offers modern features without requiring any major modifications.
What Is TSM/TSSM?
The OEM Harley-Davidson® Turn Signal Module (TSM) and Turn Signal Security Module (TSSM) are electronic components. They control your motorcycle’s turn signals, hazard lights, and—if your model has a TSSM—security features like the immobilizer and key fob recognition. Essentially, these modules manage the timing of your signals, ensure they self-cancel based on speed and lean angle, and guarantee that your turn indicators flash correctly.
However, if these modules fail, you may notice issues. Specifically, erratic turn signal behavior, signals that either don’t work or flash constantly, or even an inability to start the bike if the security system is compromised. Failures typically occur due to internal electrical problems, water damage, or simply aging components. Unfortunately, a full replacement is often necessary.
SMART TSM from Custom Dynamics
Fortunately, Custom Dynamics now offers a solution. The new SMART TSM replacement is a direct OEM substitute for several factory modules. In fact, four unique plug-and-play fitments are available. These replacements fit most early 2000s Harley-Davidson® motorcycle models. Making them an excellent choice for many riders.
Here’s a quick breakdown of the available options:
Manf. PN: TSM-1, SKU: 2050-0553

Key Benefits and Features
Now, let’s take a look at what sets Custom Dynamics’ SMART TSM replacement module apart from the competition:
Plug-and-Play Simplicity
Installation is incredibly straightforward. There is no need for rewiring or dealing with complex setups. Simply unplug the old unit and plug in the new one. It’s that easy, making the process quick and hassle-free.
Supports LED and Incandescent Bulbs
Whether you prefer old-school incandescent bulbs or modern motorcycle LED turn signals, this module handles both with ease. It supports a range of 0.24A to 6A per side, eliminating the need for a load equalizer or Signal Stabilizer™ when upgrading to BCM-compliant LED signals.
Smart Turn Signal Control
This module offers both manual and self-canceling turn signals based on several factors, such as:
Motorcycle speed
Time elapsed
Direction of turn
As a result, this smart cancellation system helps ensure accurate and safe signal shut-offs. Therefore, no more riding for miles with a blinker left on by mistake.
Hazard Light Functionality
In addition, the SMART TSM provides full four-way hazard light support, which automatically adjusts based on:
Time
Ignition position
Battery voltage
This feature ensures smarter, safer emergency signaling when you need it most.
Built-In Tilt Sensor
A particularly noteworthy motorcycle safety feature is the built-in tilt sensor. If your bike leans more than 45 degrees for over one second, the module automatically powers off the engine, disables starter & lamps when the bike is tipped over.
Disables Starter
TSM-3 & TSM-4 integrate with safety switches to prevent starting in gear without the clutch pulled
Protected and Efficient
Custom Dynamics has engineered this module with several protective features, including:
Short circuit and overcurrent protection
Low current consumption
Wide operating voltage range (11VDC–15VDC)
These features not only extend the life of the module but also help protect your bike’s electrical system.
Password Learning & Diagnostic Support
The SMART TSM is fully compatible with Harley-Davidson’s manual password learning procedure, as well as the CanDo or TechnoResearch module replacement procedure. This makes installation and troubleshooting more efficient, saving you time and effort.
Three-Year Warranty
To top it all off, Custom Dynamics backs this unit with a 3-year manufacturer warranty. This warranty provides peace of mind, knowing that your investment is protected.
Why Upgrade?
Many older Harley-Davidson models came equipped with TSSMs that included security features, but some riders found these features to be unreliable or unnecessary. The new Custom Dynamics SMART TSM, however, works without any security features, making it ideal for those who simply want their bike to run smoothly and reliably without the added complications.
Whether you’re restoring an older Harley or upgrading to modern LED lights, this TSM replacement offers factory-level performance. Plus, the added convenience of modern features.
Ready to Ride Brighter and Smarter?
In conclusion, Custom Dynamics’ SMART TSM replacement module brings cutting-edge performance to classic Harley models. It is simple to install, intelligent in design, and built to last. Upgrade today and experience a smarter, more reliable ride.

Hi, my bike is a 2004 1200cc Sportster Custom, and I need a part: the rollover sensor. That is, when the bike falls over, it causes the engine to stop. The code would be H-D P/N: 68920-01C.
I’d like a new one.
You would need to use the TSM-1 replacement: https://www.customdynamics.com/turn-signal-module-replacement-for-harley-motorcycles

Do they make a replacement tssm unit with fob for a 2005 FLHTCUI. And what does it cost and can I change it out my self and save money
Custom Dynamics’ does not offer a security module with fobs at this time.
Hoping this can really help me get my bike going
2008 flh.
tssm won’t recognize fob nor can i get it into where you enter the code.
I don’t really like that the clutch needs to be disengaged to start but I’m dead in the water and I don’t need a security system anyway.
Interested in maybe getting one of these
Thanks
