Yes... great opportunity to swap out the seals, which really requires removing the housings as Stig points out.

Make sure you protect the bumper below the lights, as all that dirt will scratch them up good,. I use blue painters tape.

Another potential snag when removing housings is that the nut retainers (captive nuts) for the two screws that hold the housing in may be seized up and the nut will spin within the nut holder. They'll be a pain to get out, then you'll really just need to replace them.
