Simultaneously about 9, the hiccup occurs based on processor level.
Unfortunately it's not so easy to make these circuits follow a specific path, depending on the aspect of your case, the circuits should be baked into flipbooks for performance nor generate some sort of seamless/tileable circuit texture add the texture to a Trail renderer following the path, and add a noise shader capable of scrolling through the texture/UV revealing the circuits as the noise scrolls through the mesh of the trail gradually over the time...
Sorry for not fulfilling your needs, and thanks for asking before purchasing!
