1. A sump pump system for illuminating a sump pump well, the sump pump system comprising:
a sump pump switch assembly including:
a float housing having a first end and second end, the float housing configured to be coupled to a sump pump drainpipe at a position sufficient to submerge the first end and second end of the float housing in a fluid in response to the sump pump well being filled with the fluid;
a first float switch coupled to the float housing and disposed at the first end, the first float switch configured to activate an impeller of a sump pump in response to the sump pump well being filled with the fluid; and
a second float switch coupled to the float housing and disposed at the second end, the second float switch configured to provide a redundant electrical switch to ensure operation of the impeller in response to the sump pump well being filled with the fluid; and
an illumination circuit encased in a waterproof body and configured to be coupled to the float housing, the illumination circuit including:
a first illumination sub-circuit including:
a first light emitting diode configured to illuminate a wall of the sump pump well in response to the first float switch being closed, wherein the first light emitting diode is disposed in parallel with the first float switch; and
a second illumination sub-circuit including:
a second light emitting diode configured to illuminate the wall of the sump pump well in response to the second float switch being closed, wherein the second light emitting diode is disposed in parallel to the second float switch.
