Sorry for my late reply. I have been using a 35 litre jaffa gourdon for cycling to work, walking to work and general shopping duties. The orange version is bright enough especially with the white alpkit logo.
I use exactly the same for my commute. Although the orange is not reflective it is pretty bright as long as I rinse the mud off every couple of weeks.
Point North sell some iron on reflective tape that might work, or if you have the 20l version you could fix some High Viz snap bands on.
