Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suggestion
Suggest you pull that unit from the car, bring it inside the house, and carefully check for intrusion areas.
Leading evidence: 'Check intrusion areas' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check intrusion areas' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I just noticed this after I got done playing in the snow:
Only in the driver's side headlight, and it has never happened before. These are the original units, and the service records don't show any bulbs being replaced, so I doubt it's just that one of the housings isn't secured correctly.
Any ideas?
Oh, and another pic just for fun:
pull the headlight out and see if the back has come loose or the blinker is out ? Thats a lot of water. I have a corner triangle which just started this game
To clarify, the water is on the outside, only the moisture is on the inside. Mostly over the fog light and then some at the bottom of the headlight housing above the turn signal.
They both were on when the condensation got in there. It's fine today though. Quite odd. I'll have to pull the headlight assembly out and see if anything is not installed correctly. Would be quite surprised though since they are all factory bulbs in there and no one has touched it.
Suggest you pull that unit from the car, bring it inside the house, and carefully check for intrusion areas. Seals have a tendency to dry out, leading to that problem. Get a hairdryer or heatgun (careful!) to slowly dry it out, or put it in your oven on a turkish towel at something like 150 or less if you have it. Then tackle the leak. Perhaps you can refresh the seals with silicon or even baby powder.
Love the second photo. Reminds me of a scene out of "Fargo."
I wouldn't worry about it. Unless you see water pooling (maybe it's the pic, but I don't see any) or it gets worse each time, you should keep in mind that the assembly isn't hermetically sealed. There is a vent on each lamp to combat condensation due to the temperature differential. Ice water in a plastic cup will sweat on a hot summer day, same principle.
I'm sure it's no big deal, but check to see if it spreads the next time you're out playing in the snow.
Yes, but don't forget that for water to condense on the inside, it takes more than just a temp differential. Somehow humid air got inside the assembly or there'd be no water beading in there, and because it's hermetically sealed, the seals have obviously been breached. I'd take Edgy's advice.
Love the snow picts!
One of the TSBs essentially says not to cover the gap at the bottom of the headlights, and not to cover the headlight lens with any film, bra, covering etc. because this is where the ventilation system gets it air to remove the moisture.
I'll say it again to reinforce my original post and Whitey's. The assembly is
NOT
hermetically sealed.
It is vented by design (on the assembly, inside the fender) and will "breathe" a limited amount of air, humid or otherwise.
Regarding Edgy's advice, it doesn't hurt to pull the ***'y and have a look at it to make sure the bulb compartment seals are seated properly. Please DON'T go at it with a hair dryer, heating device or turkish anything.
