I've been driving for ten years and have deep feelings about turning on the headlights. The correct way to turn on the daytime running lights is usually after starting the car; most modern models have an automatic mode—just turn the key or press the start button, and the lights will automatically illuminate to improve daytime visibility and reduce collision risks. For manual control, locate the light switch lever near the steering wheel marked with DRL or small lights, and gently toggle it. Don’t forget to regularly check if the bulbs are aging—if the lens gets dirty or the brightness weakens, address it promptly, especially during rainy or foggy weather when it ensures safety. I often remind friends that differences between car models can be significant—Japanese cars might be simpler, while German cars sometimes require settings in the central control menu. In short, always confirm the lights are on before starting, as developing this habit can prevent trouble on the road.
