Ok thank you, I had a delivery yesterday and kept the little silica packs for this so I will try and sort them out when the weather is a little betterOnce you have enough moisture in the headlamp it will condense out onto the coldest surface first. When the lamp heats the condensation goes back into the warmer air, which can hold more moisture.
You can use silica gel packets on a string through the lamphole if there is one, seal it up, to dry out the insides somewhat. Maybe a dry rag on a sick etc.
You can try using a dry gas, for example to replace the air in the headlamp to get better results.
Yes agreed I get a little in my my 3 Leon occasionally but it comes and goes and hasn’t caused any issues..My 2018 Leon FR occasionally has this but it clears when temperature & humidity change.
Are the LED headlamp units completely hermetically sealed - or do they have small vent holes?Once you have enough moisture in the headlamp it will condense out onto the coldest surface first. When the lamp heats the condensation goes back into the warmer air, which can hold more moisture.
