Convoy Axle Light

[Jordan Baker]

Thanks Rob

So is the light socket part the same on both ends?

Also thanks for straigtening out the cover, Those last pictures made much more sense then the first ones to me.

Yes, although it may not look it by my photo. The rubber plug that would have little spring loaded springs is presently pushed too far to the back. When centered it should have a mirror image, just enough to accept the small 6 volt bulb with two contacts. The armoured cable that attaches to it would also have the same two pin contact.

If you look back at that ebay convoy conduit and cable, you will see the two pin plug attached to the same socket (13419 with nut 13423) that I have right now. The only thing that one of ebay needs now is the washer, the adapter, and the remainder of a regular truck lamp.

Robe, Great stuff, another mystery solved.

Just to complete the system, here's the toggle switch that flips between the red tail lamp and the white disc lamp and its bracket. It mounts on the left side in the spring loop between the rear of the battery box and the license plate panel. You can just make it out in the last pic.

Bruce: Does the switch bracket have the part number Co1UC 100146 on it?

By the way, I have not forgot your request (along with others) for the drawing on the bracket. I have it here on my desk now, but I left my digital calipers in the shop, so will retrieve them tomorrow. After that, the bracket will travel on it's world tour to the UK.

Here is another view of the switch. I think this is even the same carrier.

I thought I would mention as well that Brian Asbury has the convoy lamp body (the bushing but, tube, spring and lense with gasket) listed on his parts lists. You would still have to find the socket, nut and washers to complete the assembly. The part number for the sub assembly listed on BCA's part list is CO1UC 100145B.

Alternatively you could go the easy way out. Make the hole bigger in the convoy lamp bracket and use a CMP truck marker lamp assy. A guy would have to be underneath the carrier with a mirror to see the difference.

I brought in the calipers today to make the measurements on the bracket. Everything is in millimeters. If there are any questions to the measurements, ask soon as I will be heading back to KAF in a couple weeks for another tour.

Sorry for the poor drawings....I am no draftsman.

Thanks Rob, thats great.

awesome stuff, so there was a switch between the two lamps ! never knew that.

that carrier looks blimmin complete mind....and with ME stowage setup on the battery box

i know who to see when it comes to measuring those brackets for the flimsy's

great work guys

[Jordan Baker]

Rob, just wanted to say your drawing is great. I made up that bracket today in a few hrs.

Bruce, is there any chance you could post up some dimensions for the switch cover?

[rob love]

Jordan
I hope you didn't mind everything in millimeters. I usually go with inches, but the digital caliper lends itself well to mm measurements. Saves me converting decimals to fractions in the imperial system.

Good to hear it went together easily. I see I forgot to tell you how far the holes were from the ends. Center the7.8mm holes at 9mm from the end.

Jordan, here is bruce's drawing and switch in position.

Well here is my almost complete Convoy Axle lamp. I got the adapter and light cover from Brian Asbury along with the socket from a standard early CMP rubber light. The cool thing was the ink stamping on the bulb.

Someone posted a photo of a rear light that was hung off the rear of whatever you were towing. Where was this supposed to be plugged in? On a Loyd you have a rear light and a convoy light reflecting from the centre of the rear axle which is painted white, however when the 6 Pdr is following along behind it would be totally invisable to the following vehicle....the only 6v hook up point is right the way at the front on the dash panel.

Another type of light was made for towed artillery and towed mortars but I don't know what year they were introduced. Basically it is a metal disc painted white which hangs below a heavier piece of angled metal which would rest against the bottom of the towed item's barrel. A strap wraps around the barrel to keep the device in position. And the small convoy lamps shines onto the white disc to illuminate it when plugged in via a small window while the end with a red lens also illuminates. The cable has armoured braiding and is 15-20 feet long so it can reach the dash power socket on a carrier. This example is 1944 dated on the quick-release pattern webbing strap and drawings of this item are shown in my 4.2-inch towed mortar manual along with other mortar specific accessories.

Finished making three bellmouth fittings today, there are two of these on a Mk1 carrier, one for finishing the conduit end of to the rear convoy light switch and one for the horn on the front plate. The one in the middle is the original.

Also made a brake rod spring from an original one, made from spring steel.

Trying to figure out the wiring of the tail light and the convoy light with the rear switch.

I think I got it "right" in my picture I drew up. Any input is much appreciated.

[kevin powles]

Hi Jordan, Brian Asbury once sold a rear tail light wire (short piece of wire with crimps on) I bought two of these a while back but have not figured out how its supposed to be wired into the circuit, Are you familiar with this wire?, not sure if he still sells them.

A couple of pics of the rear light switch from BP's carrier. If you click on the light switch first pic and zoom in you can see how the switch is supposed to be labelled.

I am resurrecting an old thread in the hopes of preventing somebody else from wasting a bit of metal. I used Bruce's fender drawing shown in post 43, and on looking at it, thought something wasn't right. But I went ahead and tried to make it anyway. The inner portion, which get's bent at a right angle and attached to the rear plate covering the diff is wrong. It should form a point rather than being a simple half rectangle.
