Headlight misting (badly)

[Geoff Peace]

I have a problem with both headlights misting very badly on the new model Yaris, 1.33 litre TR model. Car is only three months old. Occurs when the headlights have been on for a time, then switched off. The warm air inside contracts and draws damp air into the light through a vent in the top corner of the lamp which then condenses on the upper and lower part of the lamp and appears white. It does not look very good takes about 24 hours to clear. I was wondering if anyone knows if there is there any difference in the lamp venting system for different countries? If anyone has any ideas how to cure or lessen this problem I would be extremely grateful to hear from them.
