Thanks for this forum.... I've recently purchased piece by piece) the American Flyer set I had as a young boy and plan to display it on a 21' long shelf. I am planning to have the locomotive headlight, the caboose,  the searchlight car and a #760 bumper illuminated on this straight track.  

I have used a Bachman transformer from another train set and it powers all but the bumper. The first time I attached the bumper, the red bulb fried itself. Incorrect voltage? The Bachman transformer produces a max of 17 volts A.C.

Any suggestions? Thanks.
