a second light source coupled to a second electrical outlet, the second light source configured to generate a second output light on a second side edge of a second electrical device of the electrical devices;

a third light source coupled to a third electrical outlet, the third light source configured to generate a third output light on a third side edge of a third electrical device of the electrical devices; and

a controller communicatively coupled to the first light source, the second light source, and the third light source, the controller configured to:

determine a path to a first target location;

receive a signal from a secondary unit;

control the first light source, the second light source, and the third light source to operate between a lit state and an unlit state responsive to the signal from the secondary unit to indicate a direction of the first target location by:

illuminating the first light source in a direction of the second light source;

illuminating the second light source in a direction of the third light source; and

illuminating the third light source in the direction of the first target location;

determine, based on a location of the secondary unit, that the first target location is inaccessible; and

control the first light source, the second light source, and the third light source to operate between the lit state and the unlit state to indicate a direction of a second target location.

11. The lighting system of claim 10 , wherein the controller is configured to:

determine the first target location and the second target location; and

control the first light source, the second light source, and the third light source to blink in a sequential pattern responsive to the signal from the secondary unit.

12. The lighting system of claim 10 , wherein the controller is configured to:

determine the direction of the first target location and the second target location; and

control the first light source, the second light source, and the third light source to blink in a pattern based on the direction of the first target location and then the second target location.

13. The lighting system of claim 10 , wherein the controller is configured to

control the first light source, the second light source, and the third light source to operate sequentially between the lit state and the unlit state to indicate the path to the first target location and then the second target location.

14. The lighting system of claim 10 , wherein the secondary unit is a smoke detector, a heat detector, or a sprinkler activation signal.

15. The lighting system of claim 10 , wherein the controller is configured to control the first light source, the second light source, and the third light source responsive to an alarm.

16. The lighting system of claim 10 , further comprising:

one or more batteries configured to supply power to the first light source, the second light source, and the third light source.

17. An emergency exit lighting system for a building, comprising:

a first light source coupled to a first electrical outlet, the first light source configured to generate a first light signal;

a second light source coupled to a second electrical outlet, the second light source configured to generate a second light signal;
