An indicator lamp wire harness is a pre-assembled set of wires, connectors, and terminals designed to provide electrical connections for indicator lamps in vehicles, machinery, or electronic systems.

It ensures efficient power transmission, simplifies installation, and enhances durability by protecting wires from environmental factors such as heat, vibration, and moisture. These harnesses are commonly used in automotive dashboards, signal lights, and control panels to facilitate proper illumination and signaling functions.
