The problem (which is why I am VERY wary of aftermarket headlamps) is that most if not all sellers withold the manufacturer of the lights. Instead they'll say "OEM! or as good as Factory!" and yet do not provide if it is Spyder, KHC, TYC, ect. Even a lot of parts websites do this, so it's very easy to lose track of who makes it.
I was hoping there was a packing list or some sort of warranty paper or something that came in your KHC box to indicate the manufacturer.
Hey could you get a clear picture of the corner of one of the headlamps? It should have the KHC logo and a DOT Approved number there? Maybe we can try and backtrace it via that?
The weird thing is that those Headlamps are not listed on Spyder's website...
