Wig-wag lights
When were wig-wag lights introduced, and were they originally used for all the same purposes they are today? (Level crossings, fire stations, ambulance stations, patrolled crosings - I'm not counting overhead lane control signs on motorways.)

Prior to that the first mention of the various "STOP when lights show" plates was in the 1975 TSRGD. The plates weren't in the 1964 TSRGD, so presumably wig-wags were introduced some time between '64 and '75.
Strangely there isn't any obvious mention of the old-style white bordered wig-wag in the '75 regs, nor in the subsequent '81 regs. Perhaps those wig-wags were covered by some sort of railway regulations, although what they might have been I've no idea.

From the SABRE Wiki: Warning Sign/Advance Warning of Wig-wag Signals :
The Advance Warning of Wig-wag Signals sign (colloquially known as a Stop When Lights Show sign) is a supplementary plate used to indicate the presence of wig-wag signals at either a level crossing, swing or lifting bridge, airfield, tunnel, an emergency service station, or other places where traffic has to stop infrequently.
