For anyone else, found a great youtube footage on a fix for this, which is to use a self adhesive foam pushed between the 'eyebrow' and headlight which seals that route for water. You can then get lamps out use hairdryer to dry light out an a wire rid with cloth to clean the inside of the lens before putting headlight bulb back and back into service. Looks like a good fix, needs patience but best I have seen.
Here is the link.
