The phrase refers to the service of fitting auxiliary lamps designed for use in conditions of poor visibility, located in proximity to the user’s current location. For example, an individual searching for an automotive service shop in their vicinity that offers to install these lights would use this search query.
This type of service offers enhanced safety and visibility during inclement weather conditions such as fog, heavy rain, or snow. Historically, these auxiliary lights have improved driver safety and confidence by projecting a wide, low beam pattern that illuminates the road surface and reduces glare from reflected light. This improves the driver’s ability to see lane markings, road edges, and other vehicles.
