I am creating a simple demo of LED strip animation in Blender. Currently I'm planning to use Blender Render, not Cycles (I'm less familiar with Cycles).
I have already created LED meshes themselves (just a tiny boxes along a curve) and now I'm thinking what would be the best way to add actual lights to make them look and work somewhat realistically (at least, as it's possible in Blender Render).
Additional problem is that I'm going to add a semitransparent screen object in front of these LEDs and I'll need to achieve an edge-lit effect - to make the colors of the LEDs blend on the screen.
Should I use a material with high emit value or should I create spotlights or pointlights? And what would be the easiest way to animate the LED colors for each individual LED?
For reference of what I would like to achieve, here are two videos:
