Assuming that the lines on the road are in good condition or even exist. Uneven roads, potholes, and corners/junctions with no signage can all be a challenge is poor conditions with old style headlights ( our 2 cars have old and new style lights respectively ).

That being said while I don’t struggle much with the glare from oncoming headlights I find that visibility beyond the oncoming vehicle can be severely limited by the bright light. This often causes me to slow down and squint to be careful of any dangers beyond the vehicle.
