A repeatable set of LED lights with 4 colours. The Maya file has construction history for the wires, with path curves and diameter curve for extruding. The LED's have point lights that illuminate the bulb and surroundings, so you can make any flashing sequence you like.

The LED glass uses transmission depth and scatter, so if you scale the LED's you will need to adjust the transmission depth in the shader.

Setup to easily repeat into a long string, and then apply deformers to make the shape you need.
