Non-cheese-based bracket for B&M DToplight?

Hello,

The seatpost bracket for this lamp of mine has succumbed to dreaded metal
fatigue and remains attached to the bike only by zip-ties and tape. Though
I have replacements on order from Kinetics, they haven't arrived yet and I
was wondering if a suitable replacement bracket from someone other than B&M
is available. My LBS has nothing suitable. Ideally whatever I replace it
with should not be susceptible to such swift (five months) fatigue problems.

Can you make something out of the steel brackets they sell in B&Q?
These are pretty rigid; my TL-AU100 is attached to one.

FWIW, the fork crown B&M brackets are even worse for fatiguing. Less
than 500 miles sometimes!

A splendid idea. I'll wander down at lunchtime and have a look at what they
have. Thanks.

Touch wood, that seems to be fine so far. However I'll attach it to the fork
with a ziptie this evening to be on the safe side.

To be fair, they're supposed to be OK with the plastic B&M lamps. If
you fit a alu-bodied Schmidt E6 (which doesn't really *feel* much
heavier), the extra few grams are fatal.

Never be tempted to bend one of the brackets to avoid the cantilever
yoke,a s this shortens their life even more. Pack it out with washers
at the fork crown, and use a longer bolt, to put the bracket more forward.
