Yea, even on my '89 OEM lights, I drilled two very small holes (don't remember the size) on each of the two lower corners of the lights....a day or so in the sun and it cured it.....
although I'm sure it would suck to be drilling on your NEW lights......if they were still BRAND new..I'd probably be asking for a replacement ;-)
It's a problem with the entire overall design of the headlights, OEM or aftermarket. Ford had a TSB (Technical Service Bulletin) to address customer complaints of condensation inside headlight lenses, but not a whole lot can be done besides what was already mentioned.
