Just use one spotlight and increase its radius and lenght until it encompasses the whole neon bank.
Simple and effective, and has an added bonus of giving you more accurate results with distance field raytraced shadows, since the penumbra is directly affected by the source size and lenght

I have tried this, but can’t rotate the source shape to align the geometry light, it’s always align to the light direction…
