A light emitting diode warning signal light, the warning signal light comprising an array of light sources configured on a light support and in electrical communication with a controller and a power supply, battery, or other electrical source. The insert member may be adhesively secured into the insert recess, or the insert member and junction box body may include mutual latching features which engage upon insertion of the insert member into the insert recess to lock the insert member in the insert recess. The hybrid coupler further includes a first capacitive element and a second capacitive element. A plurality of second spools are rotatably attached to the second side of the deck plate. A gate voltage is applied to a plurality of word lines coupled to control gates of said array of memory cells.
