You know, I really don't know.
They were in my B.I.L's Porsche for quite a few years before he took out the xenon's and headlights.
They sat on his shelf for a couple more years until I asked him what to buy and he just gave the whole deal to me since he did not need them anymore.
I can try to find out but they have some age on them, don't know if they still make them or not.
