I recently got a big condensation issue, then I tried the hairdryer trick but I melted the lens.
Now there is a large swollen white patch of melted plastic on my headlight, it looks like my car has a yeast infection / acne.
If anyone has a spare drivers side headlight let me know. (black inside like this one... http://www.ebay.co.uk/itm/like/111480796759?limghlpsr=true&hlpv=2&ops=true&viphx=1&hlpht=true&lpid=108&chn=ps&device=c&adtype=pla&crdt=0&ff3=1&ff11=ICEP3.0.0-L&ff12=67&ff13=80&ff14=108&ff19=0 )
PROTIP; don't leave a hairdryer unattended against your headlight while trying to remove condensation, not even for 1 minute to collect a package off the postman.
