Which headlights should be turned on at all times for visibility to other drivers?

Low-beam lights are designed to provide adequate illumination for visibility without blinding oncoming drivers. They are typically used during nighttime driving, in low-light conditions, and during inclement weather, ensuring safety for both the driver and other road users.

Having low-beam lights activated enhances your visibility to other drivers, especially in situations where there may be shadows or reduced light due to weather conditions. This makes it easier for other road users to see your vehicle, helping to prevent accidents.

While daytime running lights can also increase visibility, they do not provide the same level of illumination needed for nighttime or poor visibility conditions. High-beam lights are too bright for general use and can cause glare for oncoming traffic. Fog lights, on the other hand, are specifically designed to cut through fog, rain, or snow but are not meant to be used in clear visibility conditions as they can be very low and directed, leading other drivers to see a less clear image of your vehicle. Thus, using low-beam lights effectively balances sufficient visibility with safety for all drivers on the road.
