Depending on the type of clearance light (as thy all can differ just a wee bit), I would remove all of the lenses to let them air out. I would then remove (if applicable) the housing attached to the hull. They will more the likely just be screwed in with self tappers.
Get yourself some marine grade quick set silicone and fill in the wiring hole, re-affix the mount and put a tiny bead around the seam. Then replace the bulbs with LED's (just a recommendation) and as installing the lenses put a small bead of silicone around each and install.
