I remembered that I had the wiring harness from a Dodge van of 1970s era in the barn. I found it yesterday and found that it had two dial lamp sockets that were the same size as used on these Philco radios. They even had slide-on shield that direct the light beam to whatever side you desire. Don't overlook your local auto salvage yard as a source for such items.
