I have aftermarket housings in my Jeep that lives under the Florida sun.
No leaks
Coating is flawless after 1 year
Wiring harness that came with them was equivalent to OEM
Beam pattern is equal to, or better than OEM
I can list a whole lot of OEM light assemblies that melted and cracked on me, maintained temps above 150F with Sylvania OEM-spec bulbs, and completely Kentucky fried their bulb sockets.
Even more whose light output and beam pattern was garbage from day one.
There are definitely some aftermarkets out there that do not hold up well at all, but the majority will do just as good.
