When should dipped headlights be used?

Dipped headlights should be used in built-up areas and during heavy precipitation because they provide adequate visibility for the driver while also reducing glare for oncoming traffic. In these situations, using dipped headlights enhances safety by allowing other drivers to see the vehicle more clearly without causing excessive brightness that can be distracting or blinding. This is especially important in conditions where visibility may be compromised, such as rain, fog, or when driving through city streets with many vehicles and pedestrians.

In contrast, using headlights during sunny conditions can be unnecessary since the natural light is sufficient. On highways, there are different visibility rules that may allow for brighter lights, while rural areas at night may also require dipped headlights, but they are more essential in built-up areas and adverse weather conditions for the reasons mentioned. Therefore, the correct context for using dipped headlights is indeed in built-up areas and during heavy precipitation, emphasizing both safety and compliance with driving regulations.
