Getting Aftermarket Fogs??

Found these on EBAY, what do you think?Would this be an easy install for the NON foglight crew.Or would going OEM be better?

I would go for some real HID fogs, one thing I might do is have the OEM wiring and switch put in without the OEM fogs, and get some nice ones. That way they turn on like factory, but brighter. Let me know if you see some bright HID's/   

Yeah i was thinking about the wiring and switch would much rather have that OEM than some universal switch that looks like it shouldnt be there. But my question is can I connect aftermarket fogs to OEM harnesses?
