My propane detector has blinking lights along with beeps. The code for the blinking lights is printed on the detector. There is a specific blink sequence (I forget what it is) for End-of-Life. I think the CO detector in the bedroom has a similar light sequence but as I recall, it doesn't beep, it SCREECHES !!!! (try that at 3 am)
