Does this code need to be so long?

An easy way to reduce code is to write a few functions. You repeat this sequence three times followed by sleep(0.2), sleep(0.2) and no sleep.

def light_show():
    ledgreen.on()
    time.sleep(.1)
    ledred.on()
    time.sleep(.1)
    ledamber.on()
    time.sleep(.2)
    ledgreen.off()
    time.sleep(.1)
    ledred.off()
    time.sleep(.1)
    ledamber.off()

for period in (0.2, 0.2, 0):
    light_show()
    sleep(period)

Of a loop. Or a combination of function and loop like this:

def countdown():
    for _ in range(4):
        ledamber.on()
        buzzer(BuzzerObj,523,0.8,0.0)
        ledamber.off()
        time.sleep(.2)
    
    ledamber.on()
    buzzer(BuzzerObj,523,0.8,0.0)
    time.sleep(.2)
    # Leave amber on

    ledgreen.off()
    ledred.on()
    # Stop power to the relay here
    buzzer(BuzzerObj,987,3.5,0.1)
    #time.sleep(10)
    ledamber.off()
    time.sleep(5)
    ledred.off()
