This looks good as well (and super cheap), but the million dollar question is how well it fits a cervelo aero post (different dimensions and shape from the SC) …
Might not be what you want but I just cut a piece of 1 inch PVC pipe in half and use a normal taillight. So light rests on rounded part of PVC then use the light strap to keep it on. Pretty easy and cost like $.50.
how wide is yours? I can measure and let you know tonight. I think if you tighten it enough, it will stay. I did that on my madden, before I bought the madden specific one

Thanks.
Width is 22mm, fore-aft is 63.5mm (rear of the post has a bit of a kamm tail).
That has some potential. But, if you have one, a question: what keeps the light from just popping out of the bracket. It kinda looks precarious, but maybe that is just an illusion:
For the TraceR (which I have) there’s a little mushroom lip at the back end of the light that stops it just sliding out. Then as far as it popping our ‘radially’ its a V snug fit into the clip - the clip say 220 degrees circumference so the light has to be pushed in for it to snap in place.
(The photo you have there is of the Flare, not the TraceR. Similar, but the TraceR is an aluminium machined body and is defo rechargeable via a micro USB port. The Flare is a bit cheaper and a molding.
Edit. The Flare has a couple of slots at the back to help it clip in
I recommend the Serfas UTL-6 Thunderbolt tail light. It’s the same width as my aero seatpost and the rubber straps easily fit around. It’s super bright and lasts a long time on the lowest blinking setting. 4-5hrs. Mine is 5 years old and going strong. Looks like the new version lasts even longer.

I actually have a seat post light and two Serfas Thunderbolt 2.0s on my seat stays. The 2.0s are brighten and last longer . . . I love them!!
this one works great on my Trek SC
pretty cheap too

The Lezyne rear light that was written up in the front page article here works pretty well on an aero section seatpost, just need to daisy chain a couple of the ubiquitous rubber loops together to make it happen…
If you don’t need the Varia (which is AMAZING!!!), maybe you can just order the mount from Garmin? Fits my 2018 P3 very well.
I have a cervelo P3 and used a Knog Blinder
It was a good fit and came with two sizes of elastics for larger or smaller seatposts. Unfortunately I lost it by leaving it on the back of my truck and driving away (took it off when the bike was on the rack). I replaced it with two other Knog lights both of which said they fit aero seat posts but neither were big enough.
I daisy chained this one but it often falls out of its magnetic holder and I have to turn around and pick it up…so I wouldn’t recommend it.
And the Cobber mentioned above was also not a large enough clasp/elastic. I put it on my rear water bottle holder and it fell off during a ride and I did t realize it till I got home so it’s gone now too.
The positive with these was no extra cord to recharge, the whole unit just plugs into a USB. f you can find the Mob light I mentioned above that’s the one I would recommend.

Jesus Christ…guy spends $10,000 on a bike and then does this. Lmao…
The Cygolite Hotrod is a simple, inexpensive option with several modes:

In my experience the battery doesn’t last as long as advertised, but still lasts plenty for long rides (5-6+ hrs in steady modes, 10-15+ hrs in some of the blinky modes). Fits well on the seat post of my Plasma 5.
Topeak taillux 30. Its tiny, brighter than I thought, usb chargeable, and comes with several mounts including aero post. Its also super light and inexpensive

I have one of those
Like many USB/LED lights, you do NOT want to look directly at it when you turn on to see* “Is this charged?”* unless you want to see a bright green line in your vision for the next 5 minutes or so, while your retina reboots
.
Have you seen this? The “wings†that latch on the aero post are adjustable.

I’ve got a lyzene light like that and have issues with the light twisting to the side. The rubber bit that hugs the seat post needs more depth to it.

Let me know if you have time to measure your clamp.
Beer and sleep won out last night LOL
I will get it to you tonight or this weekend

Good light. Aesthetics are pretty low-profile, stealthy.
BTW, the Cobber is a good light for a ROUND TUBE ROAD BIKE. I’ve had many of them, but only for that purpose.
