I'm looking for a rear light bracket for my Brooks B-17 saddle. My rack has a steady light attached, but I'd like to add a blinking light for additional safety. I have Bontrager, CatEye, Nite Ize and other lights that I can use. My rack bag doesn't have a rear loop (WHY???) so that won't help plus I don't always use my rack bag anyway.

Thank you.

I must be missing something: why not use one of the many lights that attach to the seat post?

This mounts on the saddle rails, but it is specific to the German taillights that have 50mm spaced bolt holes.

And the B17 saddle has a very short length adjustment range for saddle rails so if your saddle was unusually far forward, this might not work.

Not the OP, but seatpost mounted lights are often invisible on my bike with a tent or sleeping pad on the rack behind them.

If that's the O.P.'s setup as well, I used a cargo net to hold the racktop load. That made it possible to use a clip-on light, which would normally be clipped onto a jersey pocket, clipped on the cargo net at the rear of the bike. Alternatively, clipping the light onto a saddle bag with a loop at the rear might be high enough to clear the racktop load.

I used to commute through a college campus to and from work. And even in winter there were a lot of bicyclists. In November through January when it was after sunset on my drive home I often saw bicyclists with blinkers attached to backpacks, or strapped to a small saddle bag, or some other piece of fabric that prevented them from carefully aiming the taillights. And they were often worthless because they shined towards the sky or pavement. Typically when I saw these blinkers, it was when I was only a few tens of feet behind them. Or, perhaps they were worse than worthless because the riders may have had a false sense of security thinking that they were actually seen.

I only use taillights mounted on a rack, seatpost or seat stay so that I can carefully aim them towards where the drivers behind me are.

I don't disagree with you. However, keeping the directionality of blinky lights in mind, it takes less than a minute to aim one correctly that's attached to a cargo net, IME. The net can be stretched or retracted slightly so the tent or sleeping pad cradles the light where it needs to be.

I hear you. Instead of questioning your motives or basically calling you dumb, I'll tell you what I made for my own B-17 using parts from a local co-op.

My co-op has bins upon bins of kickstands and kickstand parts.

I used two of the top part, the part that sits over the chain-stays, and bent a little bracket, ran a bolt/nut though there and it works great, providing light over my rack and the occasional 6-pack strapped to it.

Hope that was helpful.

This looks like a fun 3D Printer Project. There are plenty out there and finding one could be tedious. Note that bikeforums.net does not have a specific area for proven bicycle related 3D printer links YET... Go Figure...

Anyway, send me some specs and I'll give it a try.

It is not mine, sold by Busch and Muller in Germany. I have no specs.

This is such a great idea! I recently got a CNC-ready Taig mini-mill, still struggling to get everything playing together but nonetheless excited for the day when I'm cadding and camming my little heart away.

Could you use something like this ? I was thinking about trying to mount a Garmin Varia Radar on my Brooks via this mount.

A simple, cheap hack is to use a thick zip tie on the 2 bag hangers, mount a light with a clip.

My bad. I left out the fact that it's for a Brompton so attaching a light to the seat post or putting a bag under the seat would interfere with the fold. The light attached to my rack is the Brompton light which doesn't blink per some/many European standards. Hence, an attachment to the B-17 rails is what I'm looking for.

The round mount above won't work for my tail lights, but the zip tie idea should work if I can keep the light fairly perpendicular to the ground.

One other option would be to add a light to your rack. Planet Bike on some (or maybe all?) of their lights include both the ubiquitous seatpost mount but also a seatstay mount for smaller diameter tubing. I cut some rubber from an old inner tube into a couple of strips, wrapped that around the rack tubing to make it as big as the seatstay mount. Photo shows I only have a reflector on the rack light bracket and two lights attached the way I describe using the seatstay mounts.



If you try this, put some tension on the rubber when you wrap it around the rack tubing to make the rubber grip the tubing better so it does not move later. I used a bit of tape on the rubber when done wrapping it so that it stayed there for the minute it took to deal with the seat stay bracket.

When touring, I like two lights in back. One is usually a spare, the other is flashing. The light on the left has a very narrow tight light beam straight back, but on a winding and hilly road I use the light on the right instead that has a wider beam.

You have to purchase the round interlocking disc for the one Mount above. You then attach your light to the Round Disc via many ways that can be done

If they are like the students I see when I drive through Dartmouth, they can't aim the lights because they have a phone in one hand and a coffee in the other.

I got one of these (example, several sources):

And used one of these to mount a CatEye taillamp:

CatEye offers a direct rack-mount taillamp, too.

The new Brompton factory saddle has a mounting point for the 'official' Brompton be-seen taillamp:

Good plan on almost any other bike. With a trifold bike, though, you'll beat the snot out of a taillamp on the end of the rack.



Ask me how I know!

I have a 3D printer, a couple of brooks and have already made a light to rear mount bracket. Give me a better description of how you want to mount and I’ll give it a go. Are you wanting to mount the light to the bag tabs at the rear of the brooks, the saddle rails, or…?

Polaris OBark

I did, and it works great, as long as you don't have a saddle bag.
