A friend of mine let me know that we can get hold of flexible "flick-on" illuminous reflective (in yellow or orange) Wrist/arm straps by ringing this number:
08457 50 40 30
I've just asked for 10. They are in high demand so may be a delay but it was such a quick and easy call and my mate said they were FAB!
Just thought they'd come in handy for the school runs etc and thought I'd share this info.
