So I own a 2006 GT and something I’ve come to find is a reoccurring issue is condensation in the headlights. I have seen that drilling venting holes have worked for some people and so when I saw my new headlights had the issue I decided to try it. Now I have only just done this today so I’m unsure if it has worked but I will make sure to update if it works. However if you try this you also need to have drain holes at the bottom to allow any water from the venting holes out.

Are these OEM headlights, or aftermarket?
Where did you drill the holes?
Check to see if you have vents on the back side of the headlight, usually a rubber 90* elbow. These allow the headlights to "breathe", and as temperature/humidity changes, running the lights warms up the inside and the vents reduce pressure and allow water vapor to escape. Do NOT seal up the vents.
Condensation is not uncommon on most headlights, but liquid water on the inside bottom IS an issue. That is usually a poor/failed seal between the clear front and the back.

Yup, both my original '03 and my junkyard '05-'06 headlights that I've now got on my car definitely have the same issue: both will occasionally have some moisture accumulate on the inside.
I run bright blue headlights (they produce an almost white light) that run quite hot; the moisture is completely gone after about 15 minutes. As such this is not really an issue and appears to be more of a quirk of how the lights have been designed manufactured.
Both my sets of lights have a little rubber hose for getting rid of accumulating water - and I suspect this is also where the moisture gets in, as the lights and engine bay cool down on a cold and damp night.
Drilling extra vent holes may or may not fix the issue, but if the vent hole is put in the wrong place you'll get dirt on the inside of the lens, and that's quite a lot worse than some condensation.

Check mentioned tubes. My previous RD got an attention of spiders and one of them made himself a home in it. Maybe they are clogged the same.
