Dimming your headlights is essential for road safety and contributes to better visibility for all drivers. When another vehicle is approaching within 500 feet, using high beams can create glare that affects the other driver's ability to see clearly. Dimming the headlights reduces this glare, enhancing safety for both drivers.

While driving in the city at night may often require lower beams due to streetlights providing additional illumination, the specific requirement to dim your headlights when an oncoming vehicle is within 500 feet is a critical rule that aims to prevent accidents related to blinding glare. Using high beams in rainy conditions can also lead to dangerous reflections and reduced visibility, which is why this situation does not specifically necessitate dimming. The notion of dimming lights at all times during the day, while not practical or explicitly mandated, does not align with the primary safety focus on preventing glare for oncoming traffic.
