I broke one of my head light lenses so I called up my local Yamaha shop and told him I needed one so he ordered it, he didnt ask what year i needed. So I went to pick it up today and it was plastic, the one I have is metal and glass. So what year do they change and are thay interchangeable? I have a 97 with the metal and glass lenses. I ordered new bulbs for 97 to 06, are they going to work. Thanks for any help you can give.
