Abstract: An alarm light integrated into the top of the handle of a portable patient monitor or other portable medical diagnostic instrument. Since the top of the handle is the highest point of the monitor, the alarm light can be clearly seen from the sides, top and back of the monitor. Because the alarm light is integrated into the handle structure, it can be easily moved with the monitor and cannot be accidentally disconnected. In addition, the structure of the handle protects the alarm light from damage during transport. The alarm light assembly includes a circuit board which supports at least one light-emitting diode and a connector for supplying electrical power to the light-emitting diode(s), and a light-transmitting plastic lens which supports the circuit board. When activated, the light-emitting diodes are visible through the lens.
