Traffic Light Signal Illustration - Red, Yellow, Green Warning Icon #198294 (License: Personal Use)

This vector-style illustration depicts a standard vertical traffic signal housing with red (top), yellow (middle), and green (bottom) lights all illuminated simultaneously-a non-standard condition often used to indicate system failure or caution. Black sound lines emanate from the right side, suggesting an audible alarm or warning tone accompanying the unusual signal state. The design uses bold outlines and flat colors for high visibility and clarity in digital or print media.

Commonly used in road safety education, driver’s manuals, traffic engineering presentations, or web articles explaining traffic signal malfunctions, pedestrian crossing protocols, or emergency response procedures. Matches user intent for visual explanation of abnormal traffic light behavior.
