Some of the wiring under the hood of a late model vehicle is encased in bright orange covering. This indicates a ________.

The bright orange covering on the wiring under the hood of a late model vehicle specifically indicates a high voltage electrical system. This color coding is intentional and is standardized in many automotive applications to easily identify systems that operate at higher voltages, such as in hybrid or electric vehicles, where high voltage components are crucial for operation.

Using color coding provides a visual cue to technicians and service personnel, ensuring that proper care and safety measures are followed when working with these systems. High voltage wiring is typically associated with components like electric motors, batteries, and power electronics, which can pose safety hazards if mishandled. Understanding this color coding is essential for anyone working in engine repair or vehicle maintenance to avoid accidental contact with high voltage systems.

In contrast, low voltage systems would not be indicated by bright orange wiring because they operate at safer, lower voltages and thus have different color cues. Signal wiring and ground wires also follow their designated color conventions and are not associated with high voltage ratings.
