Novus's 3 stage plastic polish works for me, and if I rem right techno as well.
It will take some elbow grease (I just took my headlights out and did it in my room) but they will look alot better. You can get it from
http://www.usplastic.com which is a great company.
The kit is enough to do god knows how many times, way more then you will ever use, so go out and clean all your clear plastics like I did. Any time I find a hazed plastic I bust out this stuff
Only alternatives are new lights, $$$ german spec s14 200sx glass ones (jdm will blind people as its aimed wrong), or go to a 97-98 front end hehe. Could always sand them too but they will be very hazey.
