Traffic Light Signal Diagram - Red, Yellow, Green Indicators Explained #3832147 (License: Personal Use)

This image depicts a standard vertical traffic light assembly with three circular lamps: red (top), amber/yellow (middle), and green (bottom), each featuring a grid pattern overlay suggesting LED or lens texture. The housing is matte black with side visors to reduce glare and improve visibility in daylight. All three lights are shown lit simultaneously, likely for illustrative or educational purposes rather than real-world operation.

Used in driver’s education materials, transportation safety websites, traffic regulation guides, and municipal signage documentation; matches user intent for understanding signal meanings, designing UI icons, or illustrating road rules.
