Indicator lights
An indicator light is disclosed herein. The indicator light can include a housing having at least one wall, where the at least one wall forms a cavity, and where the housing has a first length. The indicator light can also include a light guide disposed within the housing at a distal end of the housing, where the light guide has a second length that is less than the first length. The indicator light can further include a light source disposed adjacent to the light guide. The housing and the light guide can form a flame path therebetween.

5. The indicator light of claim 1 , wherein the mechanical retention feature comprises:
a guard coupled to the housing and disposed over the distal end of the housing and the light guide.
6. The indicator light of claim 5 , wherein the mechanical retention feature further comprises
an adapter disposed over the light guide, wherein the adapter is further disposed within the guard at the proximal end of the guard.
7. The indicator light of claim 6 , further comprising:
a lens disposed adjacent to the adapter and within the guard.
8. The indicator light of claim 1 , wherein the light source comprises at least one light-emitting diode (LED).
9. The indicator light of claim 8 , wherein the at least one LED emits at least two colors, wherein the at least one LED has a light output that is controlled by a control module.
10. The indicator light of claim 9 , wherein the control module comprises at least one electrical conductor, wherein the at least one electrical conductor is coupled to the light source.
11. The indicator light of claim 1 , wherein the light guide has a reflective material disposed on its outer surface.
12. The indicator light of claim 1 , wherein the housing is void of potting compound.
13. The indicator light of claim 1 , wherein the housing comprises at least one coupling feature disposed on an outer surface of the housing, wherein the at least one coupling feature is configured to couple to an electrical enclosure when the housing is disposed within an aperture that traverses a wall of the electrical enclosure.
14. An indicator light assembly, comprising:
a mounting frame; and
an indicator light coupled to the mounting frame, wherein the indicator light comprises:
a housing comprising at least one wall, wherein the at least one wall forms a cavity, and wherein the housing has a first length;
a light guide disposed within the cavity of the housing and abutting against the housing toward a distal end of the housing, wherein the light guide has a second length that is less than the first length;
a mechanical retention feature coupled to the housing, wherein the mechanical retention feature secures the light guide within the cavity of the housing; and
a light source disposed adjacent to the light guide,
wherein the housing and the light guide form a circumferential flame path therebetween.
15. The indicator light assembly of claim 14 , further comprising:
a control module mechanically coupled to the mounting frame and operatively coupled to the light source of the indicator light, wherein the control module controls an operation mode of the light source.
16. The indicator light assembly of claim 14 , wherein the mounting frame is configured to mechanically couple to an interior of an electrical enclosure.
17. The indicator light assembly of claim 14 , wherein the housing comprises at least one coupling feature disposed on an outer surface of the housing, wherein the at least one coupling feature is configured to couple to the electrical enclosure when the housing is disposed within an aperture that traverses a wall of the electrical enclosure.
18. An indicator light, comprising:
an outer housing comprising at least one outer housing wall, wherein the at least one outer housing wall forms a first cavity, and wherein the outer housing has a first length;
an inner housing movably disposed within the first cavity of the outer housing, wherein the inner housing comprises at least one inner housing wall, wherein the at least one inner housing wall forms a second cavity;
a light guide disposed within the second cavity of the inner housing at a distal end of the inner housing, wherein the light guide has a second length that is less than the first length, and wherein the light guide and the inner housing are movable between a first position and a second position within the outer housing;
a light source disposed adjacent to the light guide; and
a switch disposed in the first cavity and adjacent to a proximal end of the inner housing, wherein the switch toggles between at first state and a second state,
wherein the inner housing and the outer housing form a flame path therebetween.
19. The indicator light of claim 18 , wherein the inner housing toggles the switch when the inner housing is moved to the second position within the outer housing.
20. An indicator light assembly, comprising:
a mounting frame;
an indicator light coupled to the mounting frame, wherein the indicator light comprises:
a housing;
a light guide that is disposed within and abuts against the housing;
a mechanical retention feature coupled to the housing, wherein the mechanical retention feature secures the light guide within the cavity of the housing; and
a light source disposed adjacent to the light guide; and
a control module mechanically coupled to the mounting frame and operatively coupled to the light source of the indicator light,
wherein the control module controls an operation mode of the light source,
wherein the housing and the light guide form a circumferential flame path therebetween, and
wherein the housing of the indicator light is configured to be coupled to an electrical enclosure.
