Headlight condensation

Recently the inside of the lens on the nearside headlight unit on my TF is covered in condensation. I thought that using the headlights would help dry it out but a twenty minute drive last night failed to make much difference. It seems to be caused by temperature change rather than by rain - we haven't had much rain recently.
Now I see from the MG Rover.org forum that this is not uncommon, and I haven't yet seen a definite cure suggested. One member seems to have found an unlikely fix to the problem to me, but he claims it worked for him. He suggests removing the yellow caps behind the light cluster, drying out the thin sponge inside or replacing it and Hi Presto.
It looks to me that the sponge inside these caps, which is very thin indeed, is too keep the dust and possibly moisture out rather than to absorb any moisture from inside the unit.
Have any of you experienced this problem? What did you do to cure it? What’s the purpose to the yellow caps? Am I right in thinking they are a cover to some sort of vent?
I don’t need to use the car for a day or two, so I’ve left the caps off to see if the condensation clears.

P.S After looking around on line again, I just found this on MG Rover.org
"There are three white/translucent caps over the headlamp vents on the inside of the unit. I found that after having the lamps replaced three times without solving the problem (No offence to MGR mechanics, but the one in the North East are pretty poor) If you remove these caps then the air is balanced on both sides of the lamp glass and since removing these caps my headlights have never had any condensation problems since".
