Thanks Jules Jules, Not sure which vehicle in particular you are referring to, but most wiring diagrams will show the same. The convoy lamp is run from the rear lamp circuit. Most MV's of the period had a "rear only" position on the light switch, this fed to the back of the vehicle and a changeover switch where convoy or rear could be selected. regards, Richard Quote Link to comment Share on other sites More sharing options...
GeePig Posted May 9, 2013 Share Posted May 9, 2013 Richard, would the changeover switch be in the cab or at the rear of the vehicle? Trevor Quote Link to comment Share on other sites More sharing options...
thedawnpatrol Posted May 9, 2013 Author Share Posted May 9, 2013 My Humber................. yes, thanks Richard, funny enough the Humber wiring diagram does not show it, so really i just have to cut into the supply for Rear Light and add the change over switch. I do know the switch fits under the back body/near the rear axle. Jules Quote Link to comment Share on other sites More sharing options...

I could copy it to you. Richard Quote Link to comment Share on other sites More sharing options...

Trevor Trevor, For B vehicles it is usually at the rear, but armour has the switch at Driving position, for obvious reasons. Quote Link to comment Share on other sites More sharing options...

Lauren Child Posted May 12, 2013 Share Posted May 12, 2013 The painted white circle for the convoy light (with black numbering for unit serial number) is shown on Vehicle Marking 1943 published 20 Oct 1943. That may not be the first mention, but it is at least an indication of when it had become standard by. Quote Link to comment Share on other sites More sharing options...
