For those obsessed, as I am, with night time operations featuring full blast plant-reflecting illumination, here’s one solution to maximizing the power of light: Manco brand silver tape or Venture Tape in silver.
Manco is used by heater and air conditioner installers – get it at Home Depot, etc.
Venture tape from stain glass shops.
Both are 2" wide and work well as reflective surfaces in the roofs of passenger cars cabooses and loco interiors.
One obvious caution is to avoid open wiring contact as the tape is conductive.
