This paper consists of three parts. The first part discusses good and bad electrical wiring, its causes and effects, and the ways in which specific hindrances to good performance can be minimized or eliminated. Several examples are cited to pinpoint practices that create problems in the wiring system and to show how such problems can be avoided.
The second part covers vehicular lighting systems: malfunction and causes of failure, and ways of protecting the lighting system. Also discussed are the efforts of the industry associations to provide quality and standardization.
The final section tabulates the results of data which have been entered into a computer memory bank in regard to the cost of maintenance on the lighting system.
