I am working for a company selling LED strips, I would like to create a 3D model of the LED strips however I find it almost impossible to wrap the individual LED diodes and other components around a Helix surface. See attached picture first picture is what I have and second picture shows the product I am trying to create.

Please let me know if you know a way I can achieve a realistic model of a LED strip.

P.S. Picture L235.jpg looks like a decal, but it's actually a 3D surface.
