Thanks Chris your info is a big help. I will look at it again. There is a flat post that protrudes from the inside of the switch. Maybe that has something to do with where the bulb attaches. Does the bulb look something like a glass encased fuse with pointed ends? I'll have to pull off a dome light cover and have a look see.

Again thanks.
