My headlights fog up pretty bad when it rains out and it takes a while for them to dry out..obviously the company didnt do a very good job of sealing them so whats the best sealant i should use so no moisture can get in? Thanks.

 

Well do to the fact that these lights are not under pressure, under severe heat, or anything extreme to that sort you dont need the "best" sealant.

What im saying is, any good name brand sealant or liquid gasket will do the job. Some better then others? in this case, i think not. i bought clear liquid gasket to do my headlights when i painted the insides. all good for a year or so.

Hope that helped.
