moisture in headlight
 

Hi just bought my firs Mazda 323 F Sport ad have some moisture in my head lights how do i clear this up, please help.

I believe the lens is glued to the reflector. The glue must have deteriorated enough to let the moisture in. Another possibility is that the moisture got in through the bulb holder. The best fix would be a new headlight.
You could try this: remove the light and remove the bulb holder. Use a clean rag and tie it to a stick to get inside the light and mop up the moisture. Add silicone caulk to the seam between the lens and reflector. Put dielectric grease at any suspect spots at the bulb holder and hope for the best.
You could also put it in a large zip-lock bag and put a cup of rice in the bag. The rice acts as a drying medium.
