GTB MAN Posted April 9, 2018 Share Posted April 9, 2018 I think my WOT 3 has the right set up for 1941 . One tail & one stop both 6 watt T CORBIN Quote Link to comment Share on other sites More sharing options...
REME 245 Posted April 9, 2018 Share Posted April 9, 2018 From memory construction and use regulations at the time required two side lights, a match pair of head lights during the hours of darkness, and a minimum of one tail and one rear light. Quite if brake lights continued to be fitted throughout the war I do not know. Quote Link to comment Share on other sites More sharing options...
tyler Posted April 9, 2018 Share Posted April 9, 2018 (edited) Hi can anyone tell me what rear light setup/types would have been fitted to a 1945 Bedford OYD? As all have been replaced with much more modern stuff? Edited April 9, 2018 by tyler Quote Link to comment Share on other sites More sharing options...

wally dugan Posted April 9, 2018 Share Posted April 9, 2018 the use of the RUBBOLITE tail lights stopped early in the war it then became the practise to fit the LUCAS WD TI AND T2 these were only fitted to the off side rear also the isolation switch for the brake light was continued to be installed so if the brake light was not to be used why was it that two rear lights continued to be fitted ?

REME 245 Posted April 9, 2018 Share Posted April 9, 2018 You are indeed correct and this 1945 Bedford MW Wiring diagram from elsewhere on this Forum answers the question. I am more use to armour. Quote Link to comment Share on other sites More sharing options...
GTB MAN Posted April 9, 2018 Share Posted April 9, 2018 Diagram ok but does not show any convoy light or switch .Convoy light is connected to the rear light .But the ground cable. Goes threw the convoy switch switching on the convoy light The other way switches on the break. & tail light TONY CORBIN Quote Link to comment Share on other sites More sharing options...
64EK26 Posted April 9, 2018 Share Posted April 9, 2018 Just recieved these These are marked L-WD-T1A wonder if the A meant brake/tail ? Also a standard Tail/Brake light will fit in the Butlers casing, but not in the Lucas one. Looking into putting LED lights in them My Bedford Mw parts list doesn't actually specify whether it should be Lucas or Butlers, just states use MT3/WD/T1/W quantity 1. The axle floodlight states use one marked B-WD-AF1 (i.e a Butlers one) Also where is the Axle folllight switch on a MW ? Quote Link to comment Share on other sites More sharing options...
wally dugan Posted April 9, 2018 Share Posted April 9, 2018 The convoy light switch is on the rear most cross member to wards the off side chassis rail Quote Link to comment Share on other sites More sharing options...

Adrian Barrell Posted April 10, 2018 Share Posted April 10, 2018 Being twin contact doesn't make them tail/stop. The wiring diagram shown above indicates two wires, one of which goes to earth. Are they not just for twin contact, single filament bulbs? Quote Link to comment Share on other sites More sharing options...
Ron Posted April 10, 2018 Share Posted April 10, 2018 That is often the case Adrian, as per that wiring diagram. But the bulbs shown in the post on Sunday are actually twin filament. Which is something you don't see very often with the small globe. I guess you'd have to do some hunting to find them, or hope that a standard stop/tail bulb fits in the housing.

The wiring diagram shown above indicates two wires, one of which goes to earth. Are they not just for twin contact, single filament bulbs? Having thought about it... This is the correct bulb for both butlers and lucas WD-T1 lights (the pin lugs on the bulb are parallel and thus can be inserted either way round, modern twin element bulbs are polaraosed, using offset pins) This has two separate 6W elements ( a single 6W element bulb does not fit as the single contact does not make contact with either of the twopins in the socket) The dual elemement bulb has several advantages as it can be wired for 1) Stop(6W),Tail(6W) 2) Stop(6W),Stop(6W) = Stop(12W) 3) Single contact only Tail(6W) [also means if one element blows, you turn the bukb around and use the other element, no need for a spare] I think I have found some replacement bright LED type bulbs that will fit either fitting(will keep you posted) Quote Link to comment Share on other sites More sharing options...
David Herbert Posted April 10, 2018 Share Posted April 10, 2018 Ron, If a standard 6 / 21 W bulb would fit in the housing you would have to file one of the pins off it or modify the holder as the 6/21s have the pins at different heights to make you put them in the right way round. With a 6/6 W it doesn't matter so the pins are the same as a single 6W David Quote Link to comment Share on other sites More sharing options...
64EK26 Posted April 10, 2018 Share Posted April 10, 2018 David The standard 6/21W bulb with one lug field off does not fit in the Lucas type, it is about 4mm too long and the shroud cannot be fitted. They just fit in the the butlers one but the top of the bulb touches the redglas at the end. Quote Link to comment Share on other sites More sharing options...
David Herbert Posted April 10, 2018 Share Posted April 10, 2018 64EK26, I thought that might be the case. I suppose it is possible that a LED equivalent might be a bit shorter and of course there would be no question of it getting too hot.

64EK26 Posted April 11, 2018 Share Posted April 11, 2018 Bought some cheapo LED lights, filed the top lug off These fit nicely in both ucas and Butlers WD-T1's Bit of difference between tail and Tail and Stop Will carry on experimenting (note current draw is less than 10mA i.e. nex to nothing) Cheers Richard Quote Link to comment Share on other sites More sharing options...
