M2 blackout light
« on: November 30, 2019, 10:43:59 AM »
Does anyone know when they started to install blackout lights on the early m2s?  The ones that mounted on the radiator.   I’m curious if they would have put them on straight m2s versus a converted M2A1,  during rebuild?   I haven't seen any original war time photos of skate rail m2s having fender lights and a radiator mounted blackout light.
Does Anyone have any info on this?

Great question!  We are building our wiring harness right now and there is no wire in the M2 diagram so we thought it might be an addition with the A1 upgrades???  Our was definitely an M2 converted later and it has the driving light and bracket on the side of the radiator with fender mounted headlights....

Same thought as above. I have black out lights on the fender but not on the radiator.

The black out driving light mounted to the side of the radiator was only implemented on M2 halftracks with fender mounted headlights. This was an add on item. This was not done at the factory from what I can tell. Also, very few M2 halftracks had this item. Most halftracks that were converted to A1 also had the headlights changed unless it was a field mod conversion. The A1 refers to the addition of the pulpit, nothing else. But with that said pedestal lights, mine racks and luggage racks were some other improvements made. I think by the time the A1's debuted shielded ignition had been replaced by resistance ignition and capacitance noise suppression. In the back of David Doyle's volume 1 halftrack book is the wiring diagram for this blackout light.



sorry for the sideways photo.

That's good info Steve .  Big thank you for that.   Makes sense that a converted m2 to m2a1 wouldn't have it since it would get the pedistal lights.    I am still looking for a war time photo of a straight m2 with the radiator blackout light. Seems rare but looking though photos there were so many ad on and unique things that were done to these vehicles that whatever you want to put on or modify on a halftrack wouldn't be incorrect.    The radiator blackout lighting is one of those cool ad on items.
