Cheers,

I've been using elastic bands to keep my rear light attached to my seatpost and it serves me right, though I don't like to looks of it
Anybody care to share tricks on how to attach lights on the back of the B17 Brooks.



B17 has these "hooks" or whatever, and I guess they can be utilized for attaching rear light, though I have no clue how to search for those kinds of lights. Improvised solutions are also cool, anybody care to help?

Thanks!

Elastic bands... what kind of light are you using? The hooks on that saddle are intended for bags.

I use a Cateye that mounts to the seatpost:

I use a cheap type light from a LBS, and dislike the whole system of mounting on the seat post, since the other plastic parts always fail and brake, so I install it this way. It's darn ugly but it works and it's easy to take of when riding in the daylight, though I rarely take it of due to poor weather at this time of year, so I figured I could switch to something more elegant to install the light under the seat, or at the back of the seat. I like to see the seatpost without any plastic or whatever on it

I hang my light off of my Carradice Pendle bag that is mounted to my B17.

I also have a Spanninga tailight I mounted to my rear fender.

Not a fan of plastic, eh? Check out https://blinksteady.com/ in Brooklyn.

Note that I have no experience with the product and never heard of it prior to Googling up "bicycle seat mounted light".

Pretty damn cool light but a bit pricey for me.

Ive seen a Bag hung from the saddle loops with a stiffener panel added ,
then a couple blinkies added to the stiffener panel,
the bag was a Brompton accessory it held the cover for the Bike when folded ..

see @ Brompton yahoo group.

Hm...

Could not help myself so:


Yes, those are zip ties, after duct tape, the second thing in universe used to mend things...

Since the existing light had "tongue" used for attaching it to the plastic holder, I though of reusing that piece of plastic as to slip it in through the zip tie "holder", but as I suspected the light could tilt way to low and point to the ground so..
I found a broken part of plastic from an another ex commuting light system and figured it could be attached to the plastic tongue, but after it's been inserted into zip ties.

You can see the plastic part sticking at the back of the light, I used small duct tape to hold it for photoing.

And then - after the installation, again duct tape secures the plastic piece to the back of the lighting device and therefore omits the tilting of the unit towards the floor

I use a zipper pull for a jacket (Under $1 for 4 in the camping dept. at Wal-mart) through the saddles bag loop and clip a light to that. It swings around a bit while riding, so this method isn't good for lights that are highly directional. In fact, it hangs at an angle, but this is a secondary light and I think an angle and swinging a bit helps increase my visibility from the side.

Some of my rain gear would cover my blinkies if I mounted them onto my Brooks saddles so I mount them on the seat post. However I had problems with my PlanetBike Superflash lenses popping off when using the stock rigid mounts attached to the seat post so I now have several rings cut from an old tube slipped up the seatpost to act as both cushioning buffers and holding straps to slip the clip through.

It's not what you are asking for, but...
If you have fenders you could use the fenderbot which mounts to your fenders.

@Branimir Clean that bike
Interesting solution with zip ties and duct dape, could you post a photo of it from behind?

Buy a bicycle seat pack and clip the light on it. This works, or like me you can mount a rack and trunk bag. Same principle.

Seatpost mount is a better way to go, as is a rack mount (if you use a rack).
Seat bags are unreliable for mounting lights in my experience, because they tend to sag/bend, making the light less visible.
