GTS Headlight covers

I want to get come blackout GTS headlight covers for my teg, but im not sure where I can get the ones I need for it. is the site for the manufacture. But I was looking for some wholesale dealer or somewhere else I can get them for cheap. Any ideas? Also, I was thinking of replacing my stock fog lights with some of those after market halygens… Is it possible to simply remove the old ones and wire the new ones into the same circuit? So I can still use the button on my dash… Thanks
