Back in the olden days when I was just a boy emergency lights used to have red LEDs to indicate they were charging. These days they are always green.
Does anyone know when and why they changed colour?
I came across this fitting the other day in a scout hut, and it passed the test, whilst some of the newer fittings failed to light at all, never mind stay on.
