How to Turn on Fog Lights on Rainy Days?
2 Answers
To activate fog lights for defogging on rainy days, follow these steps: Locate the light control lever below the steering wheel; identify the fog light symbol and rotate the control ring; align the front fog light symbol to the 'on' position. Front fog lights are installed slightly lower than headlights, serving to illuminate the road and provide safety warnings during rainy or foggy conditions. Other defogging methods include: Window Ventilation: If the interior fog is minimal, slightly open both side windows to allow air convection between inside and outside the vehicle. This reduces temperature differences and gradually dissipates the fog. This method works similarly to using the air conditioner's cold air setting but without increasing fuel consumption. However, window ventilation has clear drawbacks: it's unsuitable during rain, snow, highway driving, or heavy fog conditions, and it lowers the interior temperature. Air Conditioning System: Turn on the interior fan and cooling switch; directing cold air onto the front windshield quickly eliminates fog. Defogging Spray: Apply the spray to the inner surface of the car glass and wipe it clean. This not only removes glass stains but also forms a protective film to prevent water vapor condensation and fog formation. One application can prevent fogging for about ten days.
When turning on fog lights in rainy weather, I first start the car because the fog lights require power to function. Then, I locate a button or knob near the steering wheel or on the dashboard marked with the fog light symbol, usually an icon of a light with horizontal lines beneath it. From my experience, fog lights should only be used in rainy conditions when visibility is very low, such as during heavy rain when vision is blurred; otherwise, regular low beams are sufficient to avoid reflective glare affecting others. I often remind myself to check if the bulbs are in good condition and to read the vehicle manual, as the switch positions vary between different car models—some have a rotary knob to select the fog light position, while newer models may control them via the touchscreen. When driving in the rain, fog lights help diffuse low light and reduce glare, but they should be used in combination with reduced speed and activated windshield wipers, as overall safety remains the top priority.
