Safety directional indicator
First Claim
1. A safety directional indicator system comprising:
- a flexible belt;
a plurality of elongated light transmitting bars, each light transmitting bar in the plurality with a first and second end, and each light transmitting bar disposed in parallel along the belt such that the longest side of one light transmitting bar is disposed parallel to the longest side of another light transmitting bar in the plurality and each light transmitting bar is disposed between a first and second edge of the flexible belt;
a plurality of LEDs wherein each LED in the plurality is disposed at the first end of each light transmitting bar such that there is an equal number of LEDs as light transmitting bars;
wherein each LED is disposed between the first end of one light transmitting bar and the first edge of the flexible belt; and
the first and second end of the light transmitting bar is disposed between the LED and the second edge of the flexible belt such that the light transmitting bar is separated from the LEDs while still allowing transmission of light from the LEDs through the light transmitting bar;
wherein the plurality of LEDs are in operable communication with a control system for illuminating the LEDs.

Abstract
Provided is a safety directional indicator to improve highway safety. Embodiments of the invention include devices for guiding a driver of a vehicle in a desired direction, typically away from highway workers, pedestrians, curbs, and opposing lanes of traffic. Specifically included is a safety directional indicator system comprising a flexible belt with a plurality of light transmitting bars disposed along the belt and having a plurality of LEDs disposed at one elongated end of each light transmitting bar and in operable communication with a control system for illuminating the LEDs in a manner to indicate a direction for traffic. Safety devices according to the invention can be stand-alone devices, devices capable of being attached to objects or structures at a highway scene, or configured to be worn on a person'"'"'s body. An object of the safety devices according to embodiments of the invention is to increase driver awareness of highway situations especially during conditions of restricted visibility.
