If the inside is dirty or cloudy it's probably because of a cracked headlight assembly. Unfortunately you can't really do much to clean it. I guess you could remove it, rinse it out with distilled water, blow it dry then put it back, but even that probably won't do much good. The reflective surface on the inside is very soft and will come off and/or scratch easily so don't touch it with anything.
97 tacomas do indeed have headlights.

It does not have a cabin filter.
Try cleaning the outside of the headlamp first with toothpaste... 99% of the time it appears as though its on the inside but its on the outside.

If the damage is on the outside of the lens and you have never noticed any condensation or wettness inside the headlight this is an easy fix. The 97 dodge stratus should have plastic headlights if it does then you can get them retored or restore them yourself pretty easily by just going to headlightsolution.net they specialize in restoring plastic headlights, I owned a 2001 dodge intrepid with horrible yellow headlights i tried this company now they look brand new and i can see at night once again. Good luck.
