More About "red and green lights eg crossword clue"
The clue "red and green lights eg" immediately brings to mind systems that use these specific colors to communicate directives. The most common and direct answer is "TRAFFIC", referring to traffic lights. These ubiquitous signals are crucial for urban planning and safety, dictating when vehicles and pedestrians should stop or go, thus preventing accidents and ensuring smooth flow.
Beyond road traffic, red and green lights are fundamental in many other signaling contexts.

Understanding the versatility of color-based communication is key to solving such crossword clues. When you see "eg" (exempli gratia, meaning "for example"), it implies the answer is a general category or a primary example of the given concept, rather than a specific instance. In this case, both "TRAFFIC" and "SIGNALS" fit perfectly as categories where red and green lights are prominent examples.
