Question Tail light to attach to the Specialized Pavé seat post?

Hi.

I just bought a 2021 Specialized Roubaix Sport, which comes with the D-shaped Pavé seat post. You will see how its back side is flat from the second picture in the following article.

https://www.cyclingnews.com/reviews/...atpost-review/

The current tail light I have, the Cateye Rapid 3, doesn't fit onto it because the mounting bracket is curved for a round seat post.

Does any of you know of a tail light that fits onto the Pavé seat post? I've tried a few tail lights that I have, but they all assume to be attached to a round seat post.

Thanks in advance!

If I remember correctly, some Cateye lights such as the Omni 3 came with a round plastic tube adapter accessory (it looks like a small circular plastic tube that's been cut along its length); apparently you use that piece to make a non-round part of a seatpost, round again... though they're more useful for aero seatposts shaped like fins (e.g. V-shaped, rather than D-shape in your case). If you have that piece from any of your lights, you might give it a try.

Alternatively wrap some inner tube or similar around the seat post where you want to attach your light. Or use something mouldable like Sugru?

Something like this with a silicone band attachment?

The Garmin Varia RTL 515 comes with a "D" shaped mount that fits great on my Domane SLR "D" shaped post. But it costs $200 and includes rear facing radar which probably isn't what you are looking for.

I've been pretty pleased with the See.sense lights. They are a small company but their lights have sensors to detect something coming up on you to change their light pattern/intensity and also connect to your phone via bluetooth to send a text message for crash detection. They come with various hardware for mounting and since I'm new to this site I need to post a few more times before I can share any photos! I picked these up because while I liked the Garmin Varia light the output on those was fairly weak (at least at the time).

I have the same seatpost, used the Planet Bike rubber mount so I could use my Superflash, worked perfectly:
