The aftermarket tail lights that come with a good enough gasket are more resistant to condensation, but could and probably will have the issue eventually if they aren't sealed to the housing with weatherstrip adhesive or the like.

My Colins didn't come with gaskets so I had to reuse my original shitty stock ones, and they leaked.

Once I started making my own replacement gaskets and sealing them to the housings, it didn't happen again on either the stock lights or the Colins.

My Valentis came with decent gaskets, but I still sealed them to the housings with 3M Weatherstrip Adhesive and they've been fine with zero condensation.
