Ray,
This is a difficult problem because the materials are so dissimilar and the wire is so thin that you do not have much surface area to adhere to.
My normal answer is to use E-6000 to glue metal to plastic. This might be a little messy in this application. It sounds like you were using some sort of Super-Glue ( CA ) and that is why your clear parts were fogging. Besides the fogging, was the glue you tried working for you. You can get CA glues that are supposed to not fog clear plastics. They should be available at your local Hobby Shop. Also, I've heard that coating the clear plastic in FUTURE Floor Wax will prevent the fogging.
How large of an area are you gluing? How strong does it have to be?
