Provided is a sign assembly for use in conjunction with a traffic signal. The sign assembly includes an internal power source for powering a lowering mechanism, such as a motor in driven connection with a pulley, and a sign lowering mechanism such as a standard stop sign. The sign assembly further includes a control circuit in electrical communication with the internal circuitry of the traffic signal having a sensor configured to monitor the traffic signal for power loss. The control circuit is configured to lower the stop sign when a loss of power to the traffic signal is detected and raise the stop sign when power is restored to the traffic signal. The stop sign reduces accident risk by reminding drivers to always stop at a four-way traffic signal intersection when the traffic signals lose power and become inoperable.
