Pronunciation: [blˈɪŋkɪŋ lˈa͡ɪts] (IPA) 
The spelling of "blinking lights" is quite straightforward. "Blinking" is spelled with a "k" rather than a "c," as this indicates the sound /k/ at the end of the word.

Blinking lights refers to a visual phenomenon produced by the rapid and intermittent illumination and extinguishing of light sources. It is characterized by the repeated and regular interruption of light, creating a flashing effect that is distinct and noticeable. This phenomenon commonly occurs in various electronic devices, signaling mechanisms, and lighting systems, where lights are intentionally designed to blink in a specific pattern or sequence.
The purpose of blinking lights varies depending on the context. In electronic gadgets and appliances, blinking lights often indicate the operational status, such as power on/off, mode selection, or error notifications. These lights serve as a visual cue to prompt users about the device's functioning or any necessary actions to be taken. Additionally, blinking lights in traffic signals and emergency vehicles play a critical role in directing and alerting motorists, pedestrians, or emergency responders by conveying specific instructions or warnings.
Blinking lights can also be employed for decorative or aesthetic purposes, enhancing the visual appeal of objects, installations, holiday decorations, or entertainment venues. In such cases, blinking lights are often deliberately arranged in various colors, patterns, or speeds to create a visually captivating display.
Overall, blinking lights are a visual phenomenon characterized by the intermittent illumination and extinguishing of lights in a regular and repetitive manner. They are commonly found in electronic devices, signaling systems, and decorative settings, serving operational, informative, safety-related, or aesthetic purposes.
The word "blinking lights" does not have a specific etymology, as it is a combination of two separate words. "Blinking" is derived from the Middle English word "blenken", meaning "to shine or twinkle intermittently". "Lights", on the other hand, originates from the Old English word "liht", which referred to an illuminated object. Therefore, the term "blinking lights" simply combines these two words to describe lights that appear to be flashing or intermittently shining.
