This simple electronic device transforms your home's interior holiday lights into a synchronized animated spectacle precisely matched to the rhythm and music of 20 pre-programmed Christmas carols played through the built-in speaker. Also capable of playing music while lights stay on constantly, each of the six outlets can power up to two strands of C-type bulbs or three strands of mini (T1 3/4") or LED lights, in addition to other lighted displays. Special circuitry turns the different light systems off and on in perfect synchronization as the speaker plays traditional tunes such as Jingle Bells and Deck the Halls, with 10 carols in a traditional style and 10 in a modern holiday style, creating a flashing kaleidoscopic choreography of illumination and sound. Each catalog of 10 carols plays in a random order, or specific carols can be selected at the touch of a button. 11 1/2" L x 7 1/2" W x 4 1/2" D. (3 lbs.)
