Lynn, just been through the same thing recently, the moisture on the inside means that the seal has been compromised. I have had my original lights resealed and for all the money and effort it only worked for short time. IMHO it is easier and cheaper in the long run to just save up the $700 and buy brand new headlights. I have a toyota/lexus certified mechanic that has his own business in Delray Beach, but that is too far from Orlando and not necesary, just look in the phone book for auto repair and toyota or lexus certified mechanic in your area, you should find easily find one. Good luck.
or buy a set ready to drop in from me for say $100 shipped to your door for the set, they have been painted on the inside w/ gunmetal metallic and mount just fine..........click on picture for larger image
need plastic polish on outside only
