An edge-lit light engine module for signs and a sign are provided. The light engine module has housing and a light engine that fits within the housing. The housing has a base member and at least one side member that overlaps a tab formed along an edge of a sign face. The housing is configured to align the light engine with the partial edge of the sign so that light from the light engine enters and is reflected within the material that forms the sign face so that the sign face becomes illuminated. The housing properly aligns the light engine, and also serves as a heat sink to draw heat away from the light engine and transfer the heat outside the housing.

The sign of claim 1, wherein the predetermined position between the light source and the top edge of the tab facilitates internal reflection of the light source within the planar sign face. 3. The sign of claim 1, wherein the at least one attachment element positions the at least one light source at a predetermined distance from the top edge of the tab. 4. The sign of claim 1, wherein the light guide is only attached to a partial edge of the planar sign face. 5. A sign comprising: a planar sign face;a tab comprising a light guide coupled to the planar sign face, the tab comprising a top edge (201) and having a first set of through holes formed therethrough; anda housing comprising: two opposing side members having a second set of through holes, at least a portion of an inner surface of the two opposing side members configured to be optically reflective;a base member coupled with the two opposing side members forming a channel therebetween, the channel dimensioned to receive a partial edge of the planar sign face; anda light engine configured to fit within the channel comprising at least one light emitting diode (LED),wherein the first and second set of through holes are aligned such that the at least one LED is disposed at a predetermined position from the top edge (201) of the tab to facilitate internal reflection of light emitted from the at least one LED within the planar sign face. 6. The sign of claim 5, wherein the first and second set of through holes are attached using one or more fasteners.
