Madison Universal Light Mounting Kit for Madison Pannier Racks

I recommend this product

Despite other review to the contary I did not have any problem mounting this unit and tightening the clamp sufficiently. Yes if you get heavy handed it will snap for sure and yes if you give it a brisk knock from the side it will rotate out of line. However I found the clamping force perfectly adequate for normal use both on and off road with the associated vibration not moving the unit.
Mine is fitted to the Carradice saddle bag support to allow me to add a Knog rear light and does this job well

I needed a way to fix a seatpost-mounted light to a rear rack and this does the job. Just screw on to one of the rear struts (or the rack itself) and you have a roughly seatpost-sized bar to wrap your light too. It is made of plastic but I was able to fix it securely without feeling as if I was risking somehow snapping the plastic. Very happy.

This was the second mount I bought which allows me to mount lights on the rear rack without interference from saddle bags, etc. The angle of the mount can be adjusted and it allow the use of the common rubber band type attachments Though it will adapt to different diameter tubes a rubber pad on the "jaw" would improve grip and make it harder to knock the mount out of line
This has worked very well for my Exposure Flare rear light on a Tubus rack However, the plastic cap is potentially fragile and should not be over tightened (why not metal ) and an overlapping flange on the cap would provide additional protection against the light slipping off

Does a job but really the only difference between using this and a piece of drilled copper pipe is the cosmetic finish. The grip on the vertical mounting bracket is far too weak for purpose, and can be easily knocked off-vertical. Tightening the hex nuts to prevent this simply split the plastic end-cap - very poor. If the end-cap had been metal it might have worked.

I have a Madison rack, and this fits at the back, using the two screw holes on the flat surface of the rack to create a post to mount a light unit. But it can also be used as an upright post by clamping it over any bar of a rack, and thus add an additional point for a rear light. My rear light uses its standard fitting to wrap around this upright mount so the light was really easy to fit. Great addition, I can now mount two rears for dark days, and this is a secure fitting. SJS staff explained its use to me on the phone very well, and I'm very pleased with my purchase. I didn't know any other way of fitting my lamp onto the rack.
