nopi.com has the tailights for 184 but you can find them cheaper other places...some places stop selling them so i'm not sure who is still selling'em. as far as headlights they dont sell any projector headlights for our cars. and 94's have clear corners anyways.
About the headlights, from what I know you have 4 options..
1. try to clean them whole
2. use an oven to loosen the seal and separate them, then clean.
3. there are lens cleaning and polishing kits out there that require a lot of sanding with very fine grit paper.
4. buy new headlamp assemblies.
