would they shine white along the direction the gates were open and red to where they were closed. Opening and shutting the gates would change the colour of the light displayed to road vehicles and trains.I believe these are modified level-crossing gate lamps - here's one we have at St Albans South Signal Box:
The red lights shine out at right-angles to the gate and the clear lights along the gate, thus making clear to approaching traffic on road or rail which way the gates are set.
The brackets look like modern additions to enable them to be wall-mounted - in original form there would have been a spike/socket arrangement on the top of the gate which would take the lamp but allow it to be removed for servicing.
Shirley a white lamp could be confused with any old light. would green not be better? Or could that be confused with a signal lamp?Shining a light in the open direction lets the (train) driver know that the gate really is open, and it's not the case that the (red) lamp has gone out on a closed gate. It's positive confirmation that it's clear to proceed.
Compare it to the rule to treat a colour signal with a blown bulb as if it were at danger.
its more a red=stop and a white=working properly so ignoreShirley a white lamp could be confused with any old light. would green not be better? Or could that be confused with a signal lamp?
Don't forget that at the time these lights were first used there were very few lights out of doors they might be confused with. It was only as gas lighting and the like spread that the railways moved from using white lights for 'Clear' to using green for signals and the like to avoid the confusion that had started to occur.Shirley a white lamp could be confused with any old light. would green not be better?

All level crossing lamps I've seen have either been black or red. I think these lights have been repainted as part of the adding of the wall mounting brackets. I would suggest a careful rub with say 400 grit wet and dry paper on the underside or somewhere not too conspicuous and see if traces of the original paint are lying under the green paint. (Green paint is highly unlikely to have been used by anyone connected to railway operations due to its association with a 'Clear' aspect/signal, I would have thought.)Being green, might they be army lamps? Just a thought.
