Ideal for either indoor or outdoor use, this 100-bulb Dual Color LED light set features Infinity Lights that utilize a tiny rice-size bulb built right into the light string wire. With the Dual Color system, bulbs change from warm white to multi-color and include a choice of 9 light functions. The string is battery operated (eliminating the need to be close to a power outlet and providing unlimited light display options). Includes an integrated timer (6 hours ON/18 hours OFF) for added convenience. The string has 6" spacing between bulbs for a total lighted length of 48 ft. LED bulbs are energy-efficient and long lasting.
