Abstract
Abstract A color perception tester for testing individuals in order to determine if the individual can correctly identify wires in accordance with their respective color code. The tester includes a plurality of colored wires, which, when plugged in the appropriate receptacle or plug, will cause a pair of adjacent lamps to be illuminated. Indicia is printed adjacent the plug identifying the proper colored wire which should be plugged in the circuit.

Claim 1
Independent Claim
178 words
A color perception tester for testing an individual in order to determine if the individual can correctly identify wires in accordance with their respective color code comprising: A. a source of power; B. a plurality of electrical circuit; C. each circuit including, a first and second branch, one side of each of said branches being coupled to said source of power, D. a plurality of predetermined color coded wires each having one end attached to the other side of one of said first branches, E. an electrical male connector plug connected to the other end of each of said wires, F. an electrical female connector connected to the other side of each of said second branches, G. indicia printed adjacent each circuit for identifying the proper color coded wire for the respective circuit, and H. a signal lamp electrically connected in each branch of each circuit, so that when the individual being tested plugs the correct color coded wire in a female connector according to the indicia printed adjacent a circuit both lamps in said circuit are illuminated.
Claim 2
Dependent Claim

A color perception tester for testing an individual in order to determine if the individual can correctly identify wires in accordance with their respective color code comprising: A. a source of power; B. a plurality of electrical circuit; C. each circuit including, a first and second branch, one side of each of said branches being coupled to said source of power, D. a plurality of predetermined color coded wires each having one end attached to the other side of one of said first branches, E. an electrical male connector plug connected to the other end of each of said wires, F. an electrical female connector connected to the other side of each of said second branches, G. indicia printed adjacent each circuit for identifying the proper color coded wire for the respective circuit, and H. a signal lamp electrically connected in each branch of each circuit, so that when the individual being tested plugs the correct color coded wire in a female connector according to the indicia printed adjacent a circuit both lamps in said circuit are illuminated.
Claim 3
Dependent Claim
70 words
The color perception tester as set forth in claim 1, wherein said source of power comprises: A. a step down transformer having a primary and secondary winding, B. a voltage source coupled to the primary winding, and C. said branches being coupled to secondary winding of said transformer which has potential thereon that is sufficient to illuminate said lamps but does not present a hazard with regard to electrical shocks.
