ABSTRACT:
A light device includes a base portion, a light portion having a first plurality of substantially translucent fiber optic elements and a second plurality of substantially translucent fiber optic elements, and a light source located within the base portion. A power supply may be electrically connected to the light source. The light source emits light to the first plurality of substantially translucent fiber optic elements and the second plurality of substantially translucent fiber optic elements. The first plurality of substantially translucent fiber optic elements may have a shorter length than the second plurality of substantially translucent fiber optic elements. The second plurality of substantially translucent fiber optic elements may have a modified tip region for reflecting light from the tip region. The light source may be formed by LEDs or tungsten filament bulbs. A control circuit may cause the light emitted to be constant or flashing.
