Traffic Light Signal Diagram - Red, Yellow, Green Indicators Explained #293563 (License: Personal Use)

This image depicts a standard vertical traffic light assembly with three circular lamps: red on top, amber/yellow in the middle, and green at the bottom, each housed within a black casing with gray bezels. The lights are shown simultaneously illuminated for illustrative purposes, though in real-world operation only one or two (e.g., red+yellow) are active at a time depending on the phase. The design follows international conventions for vehicular traffic regulation.

Used in driver’s education materials, traffic safety websites, municipal transportation guides, and legal documentation to illustrate signal meanings; matches user intent for understanding road rules or designing UI icons for navigation apps.
