ISO Dashboard Symbol Reference & Meaning
What Does the Symbol Mean?
The laser-etched symbol on a FILN 12mm metal symbol indicator light is a visual code used to identify a specific function, operating condition, warning, or equipment status. Instead of relying only on text, the symbol gives operators a compact and recognizable visual indication on a dashboard or control panel.
Depending on the selected symbol, the indicator may represent lighting functions, engine status, braking, battery or charging status, fuel level, temperature, safety warnings, vehicle controls, or other industrial equipment functions.
The symbol itself is a visual identifier. The electrical circuit determines when the indicator illuminates, while the laser-etched graphic tells the operator what that illuminated signal represents.
Why Does the Symbol Light Up?
When the connected equipment circuit applies the configured voltage to the indicator, electrical current flows through the internal LED and current-limiting resistor. The LED converts electrical energy into visible light.
The light passes through the internal optical lens and illuminates the laser-etched symbol on the indicator head. This creates a direct visual connection between an electrical signal and the equipment status being monitored.
Working Principle:Equipment Status → Electrical Signal → Controlled LED Current → LED Emits Light → Optical Lens → Laser-Etched Symbol Illuminates → Operator Identifies Status
How Should the Symbol Be Interpreted?
The exact meaning depends on the selected symbol and the system in which the indicator is installed. The symbol directory below includes commonly used automotive and industrial graphics such as front fog lights, high beams, engine faults, brake warnings, battery and charging faults, coolant overheating, low fuel, turn signals, parking brake, ABS, TPMS, lane departure, and many other functions.
LED color can provide an additional status cue. In common industrial applications, red is associated with danger or fault, green with normal operation or power ON, yellow/amber with caution or warning, blue with specific operating modes, and white with general or neutral indication. Actual color conventions may vary by equipment manufacturer, industry, country, and application.
