Saw one advertised on e bay last week. They’re flush at the sides, no reflector and they made with a piece at the back , which you’d have to cut to put the standard light in , or just use the two small rear/ brake lights you can buy. I think they were German made. Like a fu#*in’ numpty, I didn’t save the link , so I’m trawling Eblag , trying to find it again. They look good quality.
