Condensation in headlight

I have had this problem on my BL for a while now and have found a solution that worked for me. I think it also helps to attempt this on a dry but warm day where the headlight lens is full of water droplets. It was 28C when I did it.

I removed the high beam bulb and put the vacuum cleaner in the headlight bulb hole on the headlight assembly. Tuned the vacuum suction up to 11 and held it in place for about 20 minutes. It seemed to clean up faster when I used by finger to seal the vacuum nozzle and headlight assembly join.

This got it to about 80% clear. The stubborn droplets were coaxed out by the hairdryer set on maximum heat aimed at the problem areas. All done in 30 minutes. I suspect the upper side seal headlight seal has the leak so I've double taped it with Gorilla tape and will see how it goes before thinking about silicon. Finally happy since this has bothered me for ages.

Why Mazda can't make lights that don't suffer this problem is nothing more than a poor design executed brilliantly.
