This is the commercial lamp bracket for carrier bosses on the front fork. http://www.ison-distribution.com/ison/english/product.php?part=LBPPFK
Somebody on here had made their own from a bit of broom handle, but the worlds your onion, really.
I think Geoff means he has a horizontal bit of pipe to fit the lamp to, then at 90deg to that he has a (vertical) bit that fixes to the fork boss via a screw through the flattened bit of pipe.
EDIT we are talking about the low rider boss!
also, ID's site is confused, there's some text about a carrier on the lamp bracket page!!

Either that or they're really good at balancing large boxes....

The broom handle was me, paint it in Humbrol Matt Black and you won't notice the difference.
I did think of using a bit of dead handlebar but that requires a very long bolt, the reamed out bit of wood with a washer in the bottom works with a normal bottle cage stud.

I think Geoff.D means he has purchased a 22mm copper right-angle bend, than flattened one end and drilled it. I've got some 1" straight aluminium pipe, and intend to flatten the end, bend it and drill it, for the same purpose.

Why bend it - just mount it pointing straight out?

Because my brazeons stick out sideways.

The photo shows a mockup with a toilet roll, which is too short.

Hopeless in the wet, too.
Who is going to post the traditional way of getting a seat-post mounting rear light fitted to a carrier with no mountings?
You know the one, short bit of seatpost, cut/file a slot to fit over the alloy rod the carrier is made of (like those rustic clothes pegs the travellers used to try to sell you), bolt through to nip it up. Somebody must have one to photo?

"I'm not overweight, I'm undertall"

Sideways pointing brazeons would be a good reason...

Sorry, folks, I should have posted a photo. Lack of camera creates a problem in this respect! (memo: must get into the 21st century!)
However, 531 Colin and Snibgo have illuminated it. I did, indeed, end up with the shape that Snibgo demonstrates with the toilet roll.
The reason I went into my plumbing box of tricks is that the 90 degree bend is already made. I squeezed one of the arms in a vice to end up with a flat side and a tube side at 90 degrees. If I'd flattened a straight tube I would still have had to bend the flat side into a 90 degree, which I reckoned would weaken it along that crease, and the crease area would likely have emerged irregular in shape. What I've got is reasonbly shapely.

I think us chaps with boxes of plumbing bits should stick together....what we do on a weekend is our own business, right?
But wouldnt it be neater to use a short bit of 22mm tube, fit a capillary stop end, drill the stop end M5 and bolt it to the carrier boss with a short M5 caphead screw, preferably with a big washer under the head to spread the load. Actually, do all that in stainless, its better than ID's one!

That sounds good -- if I knew what a capillary stop end was.

Solder together....

Anyway - my lights are in 22mm end caps

Dont need 10, though

These lightfitttings are all very well bolted to a fork boss until the bike falls over and damages the fork

So I propose something a leetttle more involved but forkprotectinglygoood.
Get a mudguard stay bridge, rivet it to the m/guard in front of the fork,with one of the two rivet holes,nearer to the front of the m/guard the better, then fit two m/stays from it to the f/fork carrier bosses,so in effect making a third stay on the m/guard.Using the remaining hole in the m/g stay bracket and a hole drilled through the m/guard,bolt a short 10cm length of 22mm plastic overflow pipe to the m/guard,the o/flow pipe may need profiling (easily done with a half round file)in the middle to the shape of the m/guard profile to make the fitting more stable and proffesional looking.
The plusses are that if the bike falls over the theres less likelyhood of damage to either the lights or the fork and two lights can be fitted one either sid of the m/guard .
I haven't actually done this mod myself but have seen it done and keep promising myself i will as it looked very good and correct in a utility kind of fashion .

The dimensions to avoid this problem are fairly critical.

I like the idea of a fitting on the front end of the mudguard. But to be a "cheap trick" it should be a toilet roll and sticky-back plastic.
