Yes, the TSM-4 is fully compatible with LED turn signals and does not require a separate load equalizer. It works seamlessly with BCM-compliant LED upgrades thanks to its intelligent load detection across the 0.24A to 6A range.
No, the TSM-4 operates solely as a turn signal module and does not replace the alarm or security features of the OEM HFSM (Hands Free Security Module). It focuses on turn signal functionality while maintaining safety interlocks like clutch protection.
The TSM-4 is compatible with 2007-2013 FLT/Touring models, 2009-2013 Trikes, and 2007-2013 XL Sportster (NU designation). It is designed as a direct replacement for models using the OEM TSM 68920-07 module.
Yes, the TSM-4 features intelligent auto-cancel for turn signals based on speed, time, and direction. It also includes four-way hazard mode with smart cancellation logic triggered by timing, ignition position, and battery voltage.
The TSM-4 includes several safety features: automatic shut-off when lean angle exceeds 45 degrees for more than 1 second, clutch interlock protection that prevents starting in gear without pulling the clutch, built-in short circuit protection, and overcurrent protection on turn signal circuits.
The TSM-4 is a direct plug-and-play replacement with installation instructions included. If you have basic mechanical skills and access to the module location, installation should be straightforward. However, if you are uncomfortable with electrical work, professional installation is recommended.
The TSM-4 is designed to operate reliably between 11VDC and 15VDC, making it compatible with standard motorcycle electrical systems including those with weak batteries or during charging cycles.
