    Taillight Mounting - "Fred"-style

    I bought a taillight and strobe that had only seatpost mounts. However, I wanted to mount them on the back of a rear rack (the racktrunk bag hides the seatpost). Thought I'd share my solution FWIW.

    Slice off most of an approx-seatpost-size PVC elbow to leave a tab. Bandsaw or hacksaw, then sanding. In my case, my ancient rack has a horizontal flat area at the back. Drill holes and bolt it where desired. A "vertical" tab can be made using a straight piece of PVC. The tab is pretty sturdy BTW.

    Have you got a pic of it mounted on your rack with your bag in place?
    If at first you don't succeed, then skydiving definitely isn't for you.

    Here is a photo of my PVC pipe blinkie mount.

    1 1/4-20 bolt
    1 1/4-20 nut
    2 1/4 fender washers
    1/2" PVC plumbing pipe about 1" long.
    I cut the pipe with an angle so the blinkie would be just below anything strapped to the top of the rack that would extend over the blinkie.

    It's easier to pick a Yankee tourist than a bail of cotton.

    I haven't decided on fastener size/type yet, but here's one zip-tied in place. Sorry, it's out of focus, but you get the idea. Of course one could attach multiples of these on an aluminum bar or angle or a 2x4 or whatever....

    I've wondered about the difficulty for fender manufacturers to work a seat-post sized "bump" into plastic molds of their products so as to provide a mounting point for blinky lights that only come with seat-post attachments.

    In another thread I showed off my solution that was inspired by this guy.

    Here my Fred mount. A stock DiNotte seatpost mount with a 5mm hole drilled through it. A 30mm long 5mm hex head bolt with a wing nut and rubber backed washer hold it onto the stock plastic Topeak BeamRack mount. Below all of that is a Superflash that attaches to a PB Cascadia fender.

    OK, I have a problem with something. Who decides what is Fred and what is not. Show me the dictionary, or the fellow in the dark corner passing judgment. I don't see Fred here, I see innovation. In fact I have posted pics of some of my ideas. I am not a Fred, in fact, I am the coolest person I know.

    You are only a Fred if you let yourself be one.
    Flying an airplane is really very simple...Push the stick forward, the house gets big. Pull the stick back, the house gets small. Keep holding the stick back, the house gets big again.
