## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to safety devices and, more specifically, to safety lights for use at night by people and pets that will allow for the safe continuation of activity after dark under normally inadequate lighting conditions that would otherwise be considered too dangerous to engage in for a variety of obvious reasons.
2. Description of the Prior Art
There are numerous nighttime safety devices that provide for continued safe activity after dark, however their visibility, while adequate under some conditions, are dependant for the most part on reflected lights such as headlights and street lights for them to work effectively. The absence of adequate lighting would render these devices virtually useless and would place the user in a dangerous situation. While these other devices may be suitable for the purposes for which they where designed, they would not be as suitable for the purposes of the present invention as heretofore described. What is needed is a device that provides its own illumination and is therefore independent of ambient lighting conditions. The device should be easily and securely positionable on a variety of objects typically associated with nighttime outdoor activities.
SUMMARY OF THE PRESENT INVENTION
The present invention relates generally to safety devices and, more specifically, to safety lights for use at night by people and pets that will allow for the safe continuation of activity after dark under less-than-adequate lighting conditions which would otherwise be considered ill advised. The device is a long, linear array of small battery-powered, switch-operated lights encased in a clear, flexible, plastic tube. The tube and switch box are capped and sealed so as to be water resistant to prevent short circuits during inclement weather. The present invention is designed to be attached to a leash for use as a nighttime pet safety device or to be worn by people. The means of attachment provided include clip hooks, as well as, straps with hook-and-loop fasteners at either end. This allows for attachment to pet leashes or around the user's body using either or both means.
There are several factors that cooperate to make the present invention an effective product most suitable to its intended purpose. Its novel configuration and self-illumination call attention to the wearer. This factor alone creates a safer nighttime walking condition. Even when no motion is present, the intensity of the present invention is more than sufficient to provide adequate visibility for successful collision avoidance by motorists under normal nighttime traffic and ambient lighting conditions.
With the introduction of motion to the scenario of a pet owner and pet walking together at night both wearing the present invention, an even greater margin of safety is provided by the prominent visibility of the unusual spectacle of motion and light. The attention getting visibility afforded to the wearer is also a deterrent to crime since criminals typically look for potential victims under conditions that will not call attention to themselves or to their intended victims. In short, the present invention provides a level of safety for nighttime activity not achieved by any other device in its field.
A primary object of the present invention is to provide a safety light tube having its own power supply.
Another object of the present invention is to provide a safety light tube that will have motion in addition to self-illumination for an added measure of visibility and safety.
Still another object of the present invention is to provide a safety light tube having a flash function control means which would enable the user to change the operation of the light array between various functions that could include but are not limited to: steady on, fast flash, slow flash, sequential, and twinkle.
Another object of the present invention is to provide a safety light tube that can be worn by the user to increase visibility of police, emergency service workers, joggers, children and any other person or object that desires to increase visibility in low light conditions.
A still further object of the present invention is to provide a safety light tube that utilizes a plurality of attachment means including but not limited to clips and straps with hook-and-loop fasteners.
Another object of the present invention is to provide a safety light tube for pets that can be secured to a leash for prominent visibility using either clip hooks or hook-and-loop straps as the attachment means.
Another object of the present invention is to provide a safety light tube for people that can be secured to a belt or around the waist for prominent visibility using either clip hooks or hook-and-loop material attachment means.
