The current technology relates to an in-line modular indicator assembly. Each of a plurality of in-line modular indicators are configured to be coupled in a series with a first electrical cable and a second electrical cable. The plurality of in-line modular indicators is configured to define an electrically conductive path to transmit electricity from the first electrical cable to the second electrical cable. Each of the in-line modular indicators have detection circuits having alternate configurations and notification devices configured to provide alternate notifications.
