The problem driving with the headlights on to chase any condensation is that the water is likely to evapourate and then condense again once cold. The atmospehere inside the light has its own littla micro-climate and unless vented the problem is likely to continue. Removing the bulbs and using the hair-dryer method is the best way forward. In other words dry air blown in is more likely to force cold wet air out.
