New headlight for old Mustang
Recently bought a 2000 Mustang GT conv as a Christmas gift to myself. Everything looked great on the car except that the headlamps were cloudy. I bought new ones from 1A and had them in quickly after watching the video. Great fit and now my Mustang looks fabulous! Thank you 1A!

big improvement
so far, so good. the headlights were very easy to install on my mustang and it makes the 2004 car look a lot newer than the hazy headlights. The price is unbeatable too!
