What color are the transmit indicator lights for the radios?

• A. Green
• B. Red
• C. Amber
• D. Blue

Answer: (A)

Status indicators use color coding to show what the radio is doing at a glance. For transmitting, a green light usually turns on to confirm that the transmission is going out. That quick, visible signal helps you know you’re on air without having to listen or check other indicators. Red lights are often used for faults or when the radio is in a different state, amber can indicate standby or caution, and blue is frequently used for data or a special function. In this setup, the transmit indicator being green is the standard cue that your voice is being transmitted.
