Turn signal relays and wear sensors
Indicator relays and wear sensors are essential components in the electrical systems of trucks. They ensure reliable current switching and timely wear detection, contributing to safety and efficient maintenance planning.

The indicator relay (also known as flasher relay) acts as the control hub for turn signals and other electrical loads. It regulates the on/off cycling of circuits at a consistent frequency and prevents overloads in switches and wiring. In trucks with complex lighting setups, a dependable relay is crucial for visibility and road safety.
Wear sensors monitor the condition of components such as brake pads or clutch plates. When wear reaches a critical level, the sensor sends a signal to the dashboard, alerting the driver to perform maintenance before failure occurs — reducing unexpected downtime and improving safety.
Common applications include:
-
Switching relays for indicators, lighting, or accessories
-
Flasher relays with fixed or adjustable flash rates
-
Wear indicators for brake pads or clutch systems
-
Early warning sensors for predictive maintenance
Reliable relays and sensors help keep your vehicle operating safely and reduce unexpected service interruptions.
