Once you use halogen lights you'll never go back to tungston sealed beams. A nice setup for your '82 turbo, BTW I have one also, assuming you have the 7" round and 5" fogs, is to use a 7" E-code and a 7" Z-code Cibie as a replacement for your sealed beams. One focuses a narrow beam down the center of the road and the other throws a flared beam in front of you and off the right side of the road. The two used together make a great for great visibility.
