I have the Spyders, I love them, as mentioned by df2x4, they are glass. I have only had my maybe a couple of months and I would also go with the aftermarket wiring harness w/relays if you haven't already. Regardless of which lens you chose, AND a set of the Philips 9011 HIR bulbs for the high beam. with either lens and the harness, you will go wow,
http://www.gmt400.com/threads/spyde...ighting-in-general.36647/page-118#post-946232 is where I started asking questions if the harness w/relays were really needed. It took so tall talking by several of the people telling me yes you need the harness, I finally ordered one and now have it installed. They were VERY MUCH correct, yes I did need it and yes I believe it made quite a difference on light out put.
