Adding interior lights to passenger cars and other rolling stock can add interest and realism to your railroad.  Some coaches come with interior lights but many do not.  Adding them can be a challenge in terms of design, mounting and providing power.  This article will show a method that I have found to be very effective and easy to implement.

For our first round of tests let's start with these assumptions:

  • Lighting will be provided by "warm white" LEDs
  • The LEDs will be powered by 4 @ AA or 4 @ AAA rechargeable cells
  • 5mm diameter LEDs will be used
  • The LEDs will be mounted on the inside of each car's roof
  • As many as a dozen LEDs may be needed to illuminate a large G scale passenger car
  • The power will be turned on and off with a latching reed switch
