Pete,
This is really helpful.
Could you send me the link on eBay for the bulbs ? Do they work on both AC / DC? I could find other uses for the bulbs.
I can make that repair but I would appreciate information on how to get to the head light bulb by only removing maybe the boiler front and it appears the pilot / pilot truck.
I can take apart a post war engine but I hesitate to take apart the modern engines.
Thank for your help.
Richard
