However certain types of unit (eg class 100) were wired differentley and could not be converted. The early batch of red bulbs soon faded through pink to white with obvious operating issues!

I would put it c1976/7.

There were issues from "day one" as the initial red bulbs were not visible in bright daylight just as the white ones were not.
