Abstract
A card light assembly comprising a generally flat polymeric tray having inner and outer surfaces and a pair of ends, a peripheral rim on the inner surface, an electrochemical cell-receiving recess in the inner surface, and a LED-receiving recess at one of the ends, an annular electrical separator and a disc-type electrochemical cell in the cell receiving recess, a LED in said LED-receiving recess, the LED having two leads, one of which is in abutment with the cell and the other of which is spaced from the cell by the separator. A pressure sensitive adhesive label extends over the inner surface, and over the cell, and is adhered to the housing inner surface to thereby retain the separator and cell within the assembly. At least one of the tray and label is flexibly depressible at the separator and cell for pressing the other lead against the cell to temporarily energize the LED.
