intermittentes

Intermitentes is a Spanish term used to describe devices or signals that operate by turning on and off at regular intervals. In automotive usage, the word typically refers to the lights that blink to convey information, such as the intent to turn or to indicate a hazard.

In vehicles, intermitentes are controlled by a flasher unit or an electronic control module, activated by the turn signal lever or the hazard switch. When engaged, the lights on one side or on all sides illuminate in an intermittent pattern, often accompanied by a characteristic clicking sound. The system serves to warn nearby drivers of a planned maneuver or of a temporary emergency.

Types include turn indicators (señales direccionales), which signal a lane change or turn; hazard lights (luces de emergencia), which flash all indicators simultaneously to signal a general emergency or obstruction; and, in some models, sequential indicators that light in a directional sequence for a stylized effect. Exterior LEDs and incandescent bulbs are common implementations, with interior indicators sometimes present on dashboards as well.

Regulation and standards for automotive intermitentes vary by region. Lighting is governed by regional standards and regulations that specify requirements for visibility, color, mounting, and flash rate. A typical flash rate is designed to be noticeable without being distracting, often around one flash per second, though exact specifications differ by jurisdiction and vehicle type.

Maintenance considerations include blown bulbs, faulty flasher relays, wiring faults, and moisture ingress. Upgrading to LEDs can alter flash behavior, sometimes requiring load resistors or newer electronic modules. Historically, intermitentes used electromechanical flasher relays; modern systems frequently rely on solid-state electronics and vehicle computer control.
