Just want to know before I buy a set.

I don't see why not. One of my headlights are aftermarket and it'* cleared.

I do know that the Bosch lights can be cleared (ive done it, its on pearls car) but as for other aftermarket, i cannot say for sre, i would say its likely that you can

The sealant on the bosch that i cleared was a but harder and less gummy, so it made for a SLIGHTLY more difficult process, but im a pro, so it wasnt too bad
