Don't drive if only one light is working or if they point in the wrong direction.

Always check that all lights work, keep them clean, and change any that don't work.

Change to the less bright lights (low beams) if another car is coming towards you and is 150 meters away or closer.

If you're driving close behind another car (closer than 60 meters), use the less bright lights unless you're passing.

Use these lights if you're driving close behind another car (closer than 60 meters), unless you're trying to pass them.

Turn these lights on when it starts to get dark in the evening until it gets light in the morning. Also, use them when the weather is bad, like when it's foggy, snowy, or rainy, and you can't see things 150 meters away.

Only use small parking lights when parking. Don't use them instead of your regular lights when it's getting dark or the weather is bad.

Daytime running lights should not be used instead of headlights during poor lighting conditions, as they may cause glare for other drivers or deactivate other necessary light systems, such as taillights.

If your vehicle doesn't have daytime running lights, you'll need to turn on your headlights.
