Custom Dynamics TSM-4

The Custom Dynamics Replacement Turn Signal Module - TSM-4 is a direct OEM plug-and-play swap for Harley-Davidson TSM, TSSM, and HFSM systems. It functions strictly as a TSM without security features and supports both LED and incandescent bulbs (0.24 A–6 A per side), eliminating the need for load equalizers when upgrading to Custom Dynamics LED signals. With a simplified marrying process for select models and compatibility with Technoresearch software, it delivers manual and self-canceling turn signals based on timing and bike lean angle, full four-way hazard operation, automatic shutoff if tilted beyond 45° for more than a second, low power draw, and built-in short and overcurrent protection, operating smoothly between 11 and 15 VDC. Replacement Part for OEM Number(s): 6892007 and 6892407.

• Integrates with the OEM safety switches to prevent starting in gear without the clutch pulled.
