An illumination device for illuminating a guest check presenter has a housing having a top surface and a bottom surface connected by a sidewall; an adhesive element disposed on the bottom surface and adapted to mount the device on the guest check presenter; the sidewall separating the top and bottom surfaces by a distance (D) that is small enough to enable the guest check presenter to be closed when the illumination device is mounted on the guest check presenter; an illumination LED mounted adjacent the sidewall for illuminating the guest check presenter; a battery mounted within the housing; and a switch operably connecting the battery with the illumination LED.
