We have such coundown for years, and the solution is very simple: both sections are made of dual-color LEDs. In "red" mode, it shows the "standing man" in the upper section and countdown (seconds) in the lower. In the "green" mode, it shows the "walking man" in the lower section with countdown in the upper, together with beeping sound: "beeeep... beeeeep... beeeeep..." while the green signal lights up, and "beep-beep, beep-beep, beep-beep" when it flashes. Beeps are multi-tonal (lower frequensy is 300...350Hz), so everyone can hear it.
