Passenger car lighting

I was running a couple of my Amtrak trains tonight, and was thinking that my version of the Three Rivers would look much better going around the layout if I could get those marker lights in the rear of the Walthers’ Viewliners/Amfleets to illuminate red.

Forgive my ignorance, but I’m not quite sure how to accompli***his. I figure I could pick up power from the rails, but that’s about as far as I got. I’m not even sure how to disassemble the cars–admittedly, I haven’t really tried…Has anybody done this? Would it be relatively simple? Any suggestions would be appreciated!!!

Thanks!

PS- While on the topic, Any suggestions of how to improve the default “diaphragms” on these cars?

Try Walthers at 1-800-487-2467, Mike Federrly, ext 3267, customer service & parts.
They are in Milwaukee, Central Time.

Thanks for the info! I’ll definitely try!
