Yup - there's some difference of opinion - it was definitely an IFF system, but the controversy is over whether they were visible or IR spectrum - I found the schematic on the inside of the rear lid - AFAIK this schematic hasn't been published anywhere before - it shows the RESIN lights as simple switched and fused incandescent lamps - not any "special" kit - so they might emit in the IR spectrum mainly, but the implication is that they were ordinary visible spectrum - they are not connected via the Morse keys though (even optionally), unlike all the other lights...
