1L (One Light) The 1L unit includes an audible alarm/LED combo. When the float switch is raised, and the unit is in alarm state, the audible 90dB siren is activated, as well as a red LED.

2L (Two Light) The 2L unit includes the same audible buzzer/LED combo as the 1L unit, as well as a white power indicator light. This light is on when power is present to the Alarm unit. If the alarm is plugged into the same circuitry as the sump pump, this would let you know at a glance if the alarm unit, and the pump have power.
