What lighting is permissible so that you can be seen as early as possible in road traffic during day-light?

You answered correctly. Both dipped headlights and daytime running lights are permitted to improve your visibility to other road users during daylight. Dipped headlights make you more noticeable, especially in changing light conditions, while daytime running lights are designed specifically to help others see your vehicle during the day. Parking lights alone are not sufficient for increased visibility in regular daytime driving and are only allowed under specific circumstances, such as when the vehicle is parked. Understanding when to use these lights helps ensure you are seen early by others, improving road safety.
