Misting up foglamps D9

[grasmere59]

Why do the foglamps mist up? I fitted 2 new ones(albeit pattern parts) to my 2003 Exec last weekend and one misted up within a day without me even taking the car on the road.

Because theres no breathers on them,

if you look at the headlamps for eg, they have that small black pipe breather, fog lamps dont have them,

ive drilled headlamps /foglamps in the past, very fine drill bit, when ive been fed up with them misting up

I had one misted up and one waterlogged so i thought i fit new ones cos i was fed up with looking at them the way they were,and now i'm almost back to square one! It ruins the look of the car,my o/h has a Ford Focus with fogs and hers don't mist up at all.

My headlamps on almost every car ive had in the last 4 yrs mist up
if iput the car in my garage, leave it outside in the cold and no problem,

never knew why

Through summer time, dont have problem with misting up lights
