Problem seeing with headlights at night.

most vehicles do tarnish because they are plastic..the heat from the bulbs,combined with the sun..glass won't do that,BUT no more glass headlights or very little.YES,there are cleaners out there,but does it last,maybe like me,only lasted 6 months and the yellow was back.NO RECALL either! this was several years ago when the 3M headlight cleaner came out when i did mine.there are so called professional folks out there now doing this,$$$$..i just jumped on Ebay and got 2 NEW headlight assemblies and 2 NEW cornering lights with all new bulbs all for $49.90 with free shipping,so i'm done with the headlight cleaners! also,i use the SilverStar ULTRA - Osram Sylvania Bulbs,also from Ebay at less than 1/2 of parts store prices,which is 2 for 50 bucks at parts stores.
