Science fiction subjects often feature components such as engines and weapons that should glow when in operation. When it’s not practical to internally light these parts, I use an easy technique that produces a reasonably close simulation.
First, I cover the area with chrome Bare-Metal Foil. Then, I color it with a Sharpie or other permanent marker and seal it with a liberal coat of Pledge Future floor polish.
The marker ink is vividly colored but translucent, and the Future further diffuses the light. Ambient light passes through the ink and reflects off the foil, producing a convincing backlighting.
