I sorta think not… I looked into that with my bike (same as in the photos)… The wiring for the tail light runs up through the interior of the seat post and emerges through an opening in the top. When I examined various suspension seat posts, none of them had an opening for wires. However, I think another thread here talks about one suspension seat post maker, being able and willing to cut a small hole into their seat post shaft to let wires emerge…
