An LED (light emitting diode) traffic light's visible light may be manipulated and encoded with data. As a result, it may be used to transmit audio messages or any kind of track or road information. All LED track lights may, in theory, be utilized as communication devices. This article describes an audio information system consisting of high-brightness visible light emitting diodes (LEDs) with one or more LEDs modulated and encoded with audio messages. High-intensity light emitting diodes (HILEDs) for traffic signals have just been available on the market. For instance, a new bluish-green LED has been developed to satisfy the color and brightness criteria of green traffic lights based on US standards and other international specifications. For many years, high-brightness red and yellow LEDs have been available on the market. A receiver with a speaker is also included in the system, which is placed at a distance from the LED traffic signal. The receiver's job is to demodulate the audio information sent through optical transmission and broadcast the messages via the speaker. Intensity modulation with direct detection is used in the optical connection. The open space, wireless transmission of audio messages may be provided by an audio information system based on an LED traffic light.
