Lucas Daylight Signal Lamp - List of Changes

[Chasemuseum]

Can anyone please provide the list of changes references for the various models of electric signal lamps used during the Great War. The following is not a comprehensive list but covers the major models:

                      Mk I Electric Signal Lamp

                      Short Range Signal Lamp MK I and Mk II

                      Long Range Signal Lamp

Cheers

Regards

Very similar to the Mk II Lucas lamp but larger

Hi

 

From TNA, MUN 7/279, a list of Lamps that were used in trials for comparison, in July 1917, this does show the variety of lamps proposed.  There were further trials of lamps during the year.

Great information Mike, many thanks. This test is with the common "Short range" model also known as Lucas or Infantry model and with the Long Range model - using a variety of different bulbs and at various voltages. It shows that the Long Range model was equivalent to the German M16 Blinkgerat, which I had presumed was the purpose of adopting that model.

 

Back to my original question - does anyone have the "List of Changes" references to these lamps.

 

Cheers
