This 3D-rendered image depicts a conventional vertical traffic signal assembly with three circular lamps: red (top), amber/yellow (middle), and green (bottom), each housed in a black visor to reduce glare. The signal is mounted on a sturdy yellow-painted metal pole with a flanged base, designed for roadside installation. The clean white background isolates the object for educational or technical illustration purposes.
