One device includes a top portion, including a plurality of light emitting elements and a plurality of lateral protrusions, and a base portion including a plurality of surfaces defining a plurality of slots, wherein each slot is configured to receive one of the plurality of lateral protrusions to secure the top portion to the base portion. ## Claims ### Claim 1 A runway lighting apparatus, comprising: a top portion, including a plurality of light emitting elements, a plurality of lateral protrusions, and a substantially square-shaped wrench receiver on an exterior surface of the top portion configured to receive a wrench; and a base portion including a plurality of surfaces defining a plurality of slots, wherein each of the plurality of slots includes a vertical portion terminating at a respective horizontal portion, wherein each slot is configured to receive one of the plurality of lateral protrusions to secure the top portion to the base portion, and wherein a distance of the horizontal portion of each respective slot corresponds to a rotation of the top portion between 25 degrees and 45 degrees to secure the top portion to the base portion. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the base portion is configured to be secured below a surface of a runway. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the base portion includes a pin, and wherein the top portion includes a surface defining an opening configured to receive the pin. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein the pin is biased in a raised position by a spring. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein the opening is configured to receive the pin when each of the plurality of lateral protrusions is located at a respective end of a horizontal portion of a respective slot of the plurality of slots. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the plurality of lateral protrusions comprises a first lateral protrusion directly opposing a second lateral protrusion. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the plurality of lateral protrusions comprises a first lateral protrusion and a second lateral protrusion that is offset from directly opposing the first lateral protrusion. ### Claim 8 A method of providing runway lighting, comprising: providing a top portion of an apparatus, the top portion including a plurality of light emitting elements and a plurality of lateral protrusions; and providing a base portion of the apparatus, the base portion including a plurality of surfaces defining a plurality of slots, wherein each slot is configured to receive one of the plurality of lateral protrusions; inserting the top portion into the base portion such that the plurality of lateral protrusions pass downward through vertical portions of the plurality of slots; and rotating the top portion, using a wrench partially inserted into a substantially square-shaped wrench receiver on an exterior surface of the top portion, in a first direction between 25 degrees and 45 degrees such that the plurality of lateral protrusions pass through horizontal portions of the plurality of slots until a pin of the base portion passes through an opening of the top portion. ### Claim 9 (depends on 8) The method of claim 8, wherein the method further includes: depressing the pin of the base portion such that the pin no longer passes through the opening of the top portion; rotating the top portion in a second direction such that the plurality of lateral protrusions pass back through the horizontal portions of the plurality of slots; and removing the top portion from the base portion such that the plurality of lateral protrusions pass upward through vertical portions of the plurality of slots. ### Claim 10 A runway lighting system, comprising: a runway lighting apparatus, including: a top portion, including a plurality of light emitting elements, a plurality of lateral protrusions, and a substantially square-shaped wrench receiver on an exterior surface of the top portion configured to receive a wrench; and a base including a plurality of surfaces defining a plurality of slots, wherein each of the plurality of slots includes a vertical portion terminating at a respective horizontal portion, wherein each slot is configured to receive one of the plurality of lateral protrusions to secure the top portion to the base, and wherein a distance of the horizontal portion of each respective slot corresponds to a rotation of the top portion between 25 degrees and 45 degrees to secure the top portion to the base; and a computing device connected to the runway lighting apparatus and including: a memory; and a processor configured to execute executable instructions stored in the memory to control operations of the light emitting elements. ### Claim 11 (depends on 10) The runway lighting system of claim 10, wherein the base includes a securing mechanism configured to engage an opening in the top portion to prevent rotation of the top portion with respect to the base. ### Claim 12 (depends on 11) The runway lighting system of claim 11, wherein the securing mechanism includes a pin protruding from an interior surface of the base. ### Claim 13 (depends on 10) The runway lighting system of claim 10, wherein the base includes a bulbous portion configured to anchor the base in concrete below a surface of the runway. ### Claim 14 (depends on 13) The runway lighting system of claim 13, wherein the top portion, when secured to the base, extends above the surface of the runway to a height not exceeding 6.3 millimeters.
