Some of you might recall that my rear light snapped off on a
recent ride. Being reluctant to throw things away if they can be fixed I decided I had nothing to lose by attempting a repair.
This design of light has plastic runners which the bike mount slots into. One of these had snapped off when I last used it and glueing it back was not an option as it would not create a strong enough joint. Instead, I took a strip of brass and have bent it to shape to match the original runners. This has been adjusted so it is a snug fit on the mount and fastened on to the lamp body in place of the originals with some car trim tape.
My modified lamp with another of the same design to compare. The strips in the middle are what's left of the old runners.
It fits
and securely enough that I can be confident it's not going to jump off the first time I go over a bump.
