Water on the inside of the housing indicates a leak. The watrer seems to
the inside of the plastic and is nearly impossible to clean out completely. The
will eventually get on the bulbs and shatter them. I usually just replace the
housings, they're not really expensive aftermarket. Here's some examples from
Itam numbers 8003465231 and 8003515111 are $80 total with shipping. They offer
pair for $99 including shipping(?).
I got new housings from a local supplier for a 92 Tempo that I once owned for
each. For that price, why bother trying to clean, polish, and fix the leak in
ones and still have lenses that will yellow again quickly.
