What type of circuit is represented by the diagram shown in the illustration? EL-0058

Correct Answer: Option D — navigation running light circuit

Navigation light circuits are strictly regulated under COLREGS and 46 CFR Subchapter J. These circuits must feature redundant power sources and monitoring systems to ensure immediate notification of lamp failure. The diagram EL-0058 illustrates the typical configuration of a navigation light control panel, including the necessary alarm and switching logic.
