Daytime running lights (which are now mandated in many countries) and headlights are distinct, separate and independent from each other – the former are not as intensely bright (and are oftentimes LED contour light or a separate, dimmer globe – at least on cheaper vehicles) and the latter are activated by a sensor when the ambient luminosity drops below a certain threshold «on top» (so to speak) of the daytime running lights.
