Collection: turnsignal modules

A tiny electronic unit determines the flashing rate of your turn signals – and it's precisely this rate that immediately reveals if something is wrong. The turn signal module (flasher relay) regulates the flashing frequency of the turn signals, and in many modern designs, it also aids in troubleshooting: if a bulb burns out or an LED turn signal operates with a different current than what the original relay was designed for, the flashing speed typically accelerates or doesn't work at all. In more modern Harley-Davidson models, the system goes even further: the TSM (Turn Signal Module) and TSSM (Turn Signal Security Module) units not only control the turn signals but also integrate the motorcycle's alarm system, starter lockout, and other safety features into a single module. If these fail, it can affect not only the flashing but often the motorcycle's ability to start or the alarm's operation. Our range includes turn signal modules, TSM and TSSM units for Harley-Davidson, Indian, and metric custom motorcycles, from factory-specification replacement parts to electronic flasher relays optimized specifically for LED turn signals. Modules with adjustable flashing speed, error-free (no-error) designs, and model-specific TSM/TSSM units that precisely fit the original electrical system of the given motorcycle are available. Quality modules ensure stable, reliable operation so that your turn signals – and, where relevant, your security system – always function accurately and predictably. Whether your goal is to repair a malfunctioning turn signal or replace a faulty TSM/TSSM module, you will find the part that precisely solves the problem with us.
