This simple electronic device transforms your exterior 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. 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. The weatherproof device withstands the rigors of winter, and has built-in volume control and a transparent cover to protect light plug connections. Mounts to the side of your house or on its ground stake, and plugs into AC. Can also be used indoors.
