Rosins ?

I believe they were a type of infrared identification light, fitted to RAF night fighters late in the war. You needed an infrared viewer to see them.

Hi Bill,

What do you mean by "late in the war"?
The report I'm talking of is dated August 1943.

Sorry, brain fart there. It appears Resin were simply coloured lights, in use as early as 1941. There were experiments with infrared lights in 1944, but apparently under a different name.
