These versatile strings or LED lights are made for signs, displays, entertainment venues, emergency exit lighting and other applications. The LEDs run off 12V dc current, and last longer, use less power, and put out less heat than standard incandescent bulbs. The modules can work alone or in groups of up to 100 units. They are impervious to shock, vibration, frequent switching and environmental conditions. They can be attached to a surface with either double-sided tape or with two screws per module (not included).
