Moisture in headlights
Perhaps check in the engine bay to make sure all the headlight bulb access covers are secured properly on the rear of the headlights. I think modern headlights usually have a vent on them so they should dry out by themselves.

In some cars, some moisture in a tail light is normal after some rain. I once read about it in a Mazda service manual. I am not sure about headlights. For the headlight, just drive the car with the headlights on even during the day. The heat from the bulbs should help the moisture evaporate quicker. If you find that your headlight is constantly getting moisture in it, then you may have a seal problem. Make sure all bulb covers are on properly.
