TSM-3 Indicator Module by CUSTOM DYNAMICS — directly replaces OEM TSM, TSSM, and HFSM modules on many Harley-Davidson models. Designed for riders switching to LED indicators or looking for a compact and reliable module for the road, this module installs in a plug-and-play manner and is sold individually.
- Compatibility: designed for Harley-Davidson (see compatible motorcycle list), Vintage/Classic and Touring.
- LED & incandescent bulbs: manages a load of 0.24 A to 6 A per side — often eliminates the need for a load resistor or stabiliser when switching to Custom Dynamics LEDs.
- Cancellation functions: manual and automatic cancellation based on time and lean angle of the motorcycle. Note: this module operates only as TSM, without advanced safety functions.
- Hazard lights: full management of warnings.
- Safety and durability: built-in protection against short circuits and overcurrents, low power consumption. Operating range: 11–15 VDC.
- Configuration: simplified pairing procedure on certain models; compatible with Technoresearch software for adjustments.
- Vehicle safety: integrates with original safety switches to prevent starting in gear without disengaging the clutch.
Manufacturer reference: TSM-3. Ideal for equipping Harleys such as the V-Rod Muscle and Night Rod Special (see model-by-model compatibility).
