Remove the headlight, clean it in and out, run a bead of automotive silicone sealer or FLOWABLE SILICONE around the joints of the two halves.
Make sure the vent hose is in place and points down.

If you must know where it leaks or to check it when the job is done, fill it with water and check for leaks around the seals of the two haves.

Use long medical Q-Tips dipped in Stoner's Invisible glass to scrub the inside of the lens.

If the lens is opaque, do a restoration per this thread

Also, check that there are rubber washers where the bulb holders fit into the capsule.

All along, remember that the going rate for these Allante headlights is $700 new, $350 used - EACH.
Darn well worth the effort.

This works for just about any headlight and tail light assy of just about every modern car on the road.
