Abstract
Abstract This specification discloses a multiple anticollision light system for an aircraft having a cockpit timer module, a power supply and decoder module, and a combination light assembly or module connected thereto. The timer module is mounted in the cockpit and serves to emanate a pulse along the original or new indicator light wiring system to the power supply and decoder module. The power supply and decoder module decodes the original signal as emanated from the timer module and serves to trigger a high intensity light in a combination light assembly. The high intensity light sends out a high intensity beam so that aircraft in surrounding relationship can effectively detect the presence of an aircraft bearing the lighting system of this invention. As an additional feature, the invention incorporates the usage of the original wiring of the aircraft so that the entire aircraft does not have to be disassembled or rewired.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
138 words
Apparatus for providing a warning light system to an aircraft having electrical power, comprising: at least one position indicator light and high intensity light mounted on the aircraft; wires internally located within said aircraft leading to the respective wing tip areas for electrical connection to the position indicator lights and the high intensity light; means connected to said wires to generate a signal of a preestablished frequency thereon; means to connect said wires to the power of the aircraft for powering said position indicator lights and said high intensity lights while said pre-established frequency signal is being generated; and, frequency detection means connected to said wires and said high intensity light for responding to said signal which is generated to cause said high intensity light to be lit at the same time said position indicator light is lit.
Claim 2
Dependent Claim
138 words
Apparatus for providing a warning light system to an aircraft having electrical power, comprising: at least one position indicator light and high intensity light mounted on the aircraft; wires internally located within said aircraft leading to the respective wing tip areas for electrical connection to the position indicator lights and the high intensity light; means connected to said wires to generate a signal of a preestablished frequency thereon; means to connect said wires to the power of the aircraft for powering said position indicator lights and said high intensity lights while said pre-established frequency signal is being generated; and, frequency detection means connected to said wires and said high intensity light for responding to said signal which is generated to cause said high intensity light to be lit at the same time said position indicator light is lit.
Claim 3
Dependent Claim
