Home-brewed rear blinky bracket?
My seat bag leaves no room on the seat post to mount a blinky. My seat stays are oval and the mounting bracket won't fit on them. If I open the zippers on the seat bag slightly, and clip the blinky into the opening, over the back of the bag, it points at the ground and the zippers tend to work their way open further.
Has anyone made their own mounting bracket? Bonus points for something that would allow the blinky to pivot up and down. I'm thinking about making a metal bracket that would mount on the top of the seat post, extending back between the saddle and the top of the bag.

I fabbed a bracket once that used a riv nut on the inside of the seat stay above the brake bridge, that was originally intended for a rack mount. Cut the flat shape, sort of a banana shape, out of aluminum then put a 90 degree twist in it. Drilled one end to fit the bolt for the riv nut and the other end to fit the threaded stud on the back of my blinkie. No longer run that mount, so I do not have a pic.

If your frame has a hole in the seatstay bridge, there are metal reflector brackets that can mount there, but without a photo of your bike, it's uncertain whether that'll work. Pics?
Unused rack mounts on the seatstays or dropouts are another possibility.

It's a road bike, the seatstay comes down in one large tube and splits just above the wheel. There are no rack mounts to attach to.
I can mount the blinky to its bracket, and put that on a short piece of PVC pipe which I can cram in the back of the bag, again with the zippers slightly open. It seems fairly stable and I can adjust the pivot angle that way. Not a long term solution of course.
The top of the bag is a hard plastic, maybe I'll attach a mounting arm to that. I don't want to start cutting and drilling into the bag till I've thought about it some more.
Sorry about the fuzzy pictures. But you get the idea.

One option here is to run down to the LBS and see if they have a reflector bracket that can be sandwiched between your rear brake caliper and the frame. Once that's in place, you can bolt a Planet Bike blinkie holder onto the reflector bracket, then drop your SuperFlash into it. Or, you can use two or three decent zip-ties to zip-tie the SuperFlash to the reflector bracket. From the photos, it looks like your blinkie would end up firing above the tire, but below the seat bag.
Hope that helps

Are your dropouts threaded for racks/fender? You may be able to use a bolt to attach the blinkie holder into there.
You could sew a blinkie tab onto your seat bag.

I thought a bracket on the brake hardware, but 1) the light would be buried under the bag, and 2) if mounted vertically, there's not enough clearance between the bag and the wheel anyway.
After staring at the hardware for a while, I think I'll take a scrap of sheet metal, screw it to the inner floor of the bag, and bring it out through a small slit. Then cut/bend it so it points up, and screw the blinky mount clip to that (instead of to the sleeve that would go around the seatpost). Maybe I'll find something already bent like that in a junk box. That oughta do it.
The problem with a tab or loop on the bag is that you can't really adjust the angle of the light. Just like when I clip it over the open zipper and it points down toward the ground.
