I thought speed cameras had to be painted yellow to make them highly visible. We've got quite alot across Tameside which are quite dark in colour. I was told the other day they're all dummy cameras. I'm not about to go testing them but this does have a ring of truth about it, especially the one with the big LED board in front of it that flashes you're in a 30 zone, even if you're doing 10mph. Anyone got any pearls of wisdom?
