Claim:
A LED sign for urban transit vehicles comprising a substantially vertical array of light emitting diodes; a cover overlying the entirety of the substantially vertical array of light emitting diodes, the cover comprising a substantially flat sheet formed from stainless steel which defines a predetermined plane; a plurality of louvers for shielding the light emitting diodes from excessive light, each of the louvers comprising a portion of the stainless steel sheet that is integrally connected to the stainless steel sheet, the louvers having a first position wherein the louvers are positioned in a same plane as the plane of the cover and a second position wherein the louvers are bent into a predetermined angle relative to the plane of the cover, wherein once the louvers are moved from the first position to the second position they remain in the second position; and wherein the cover further defines a plurality of apertures to facilitate viewing of the light emitting diodes therethrough when the plurality of louvers are in the second position, each of the plurality of louvers located within a corresponding aperture when the plurality of louvers are within the first position before moving to the second position, each of the plurality of apertures defined by a space remaining in the cover when a corresponding louver moves from the first position to the second position.
