Poor plastic headlight lenses get "beat up" from both sides. The heat in the sun during the day, sand and dust on the road hitting it at highway speeds, waxes that shouldn't be on hot plastics. At night the cool weather hitting the outside while the inside is getting heated up from the lamps. The plastics are old and will fog over impairing how much light is produced. Thus your visibility!
