Disco's back baby! The light on this alarm clock fades from one color to another much the lighting of the retro jukeboxes of years ago. The numbers of the clock are black and appear on the surface of a mirror. Protecting the mirror is a thick piece of 3/4" clear acrylic. The alarm clock is made of white plastic with silver colored buttons. This clock operates on 3 AAA batteries that are included. The light stays on for 30 seconds after pressing the snooze button, or it can be set to remain on continually. The clock measures 3-1/4" wide x 3-1/4" tall x 2" deep.
