Milt, Steve, and Buck -
Thanks for the info!
I was afraid I'd need to swap rings. Can't imagine how the chrome ones would look when all the other trim is black. I'll probably get the primered rings and paint them to match.
I didn't know about the electrical connectors, so that helps.
I assume I'd need the relay if some of those 100W bulbs happened to fall into the socket by accident........
Thanks,
G
