Notes on Meaning

• Temporal Meaning: The primary meaning is tied to the time of day (dusk/evening) when artificial lighting becomes necessary. It's less about the simple action and more about the scheduled or customary time for that action.
• Contextual Meaning: While the literal translation involves "red" (đỏ), the phrase does not typically mean "to make red" or "to show a red light" in everyday modern usage. That meaning is reserved for specific technical or signaling contexts (e.g., traffic lights, alarms). The common usage relates to illumination at nightfall.
