I have paired down my O-gauge 3-rail to two locomotives. I still have a Williams FM and an SD-45. They run fine but my SD-45's lights are barely visible. I removed the shell and ran it and both light come on but  hard to see when it is running. I hate to put a lower voltage light in as it might melt the shell. I can live with the problem but I would like a bit more illumination. Any advice?

Original Post

Connect the motors electrically in series.   The engines will not be speedsters and the higher voltage required to run them will brighten the bulbs.
