Indikaatortulede, also known as indicator lights or warning lights, are small visual signals found on a vast array of electronic devices, vehicles, and machinery. Their primary purpose is to communicate the operational status, potential issues, or readiness of a system to the user. These lights typically range in color, with common hues including red, yellow, green, and blue, each often signifying a different category of information.

Red indicator lights are frequently used to denote a critical problem, a malfunction, or a situation that requires immediate attention. For example, in a car, a red oil pressure light indicates a serious issue with lubrication. Yellow or amber lights usually serve as warnings, suggesting that a system is not operating optimally or that a component requires attention soon, but not necessarily with extreme urgency. A check engine light in a vehicle is a common example. Green indicator lights generally signify that a system is functioning correctly, is active, or is ready for use. Power lights are often green. Blue lights can sometimes indicate specific functions, like Bluetooth connectivity being active, or a specific operational mode.

The presence and design of indicator lights are crucial for user interface and safety. They provide a quick and intuitive way for individuals to understand the state of complex systems without needing in-depth technical knowledge. Manufacturers use standardized color codes and symbols to ensure clarity and reduce the likelihood of misinterpretation, thereby enhancing user experience and promoting proactive maintenance or corrective action.
