If you are driving on an insufficiently lit road outside a built-up area at less than 40 km/h, which lights are you required to have on?

Correct answer: Low-beam headlights, at least.

Below 40 km/h, high beams are no longer required, even if the road is poorly lit. You must use at least low beams along with your position lights. In the image, you are driving at 32 km/h on a dark road.
