Bought an interior light assembly on spec as it looked very similar to the one shown in the workshop manual. See picture below.
Although it looks identical in form and shape to the above figure I think it is a smaller version meant for a vehicle with hinged doors. While it is switch operated it also has an additional ground connection for the lamp to be operated by a door opening. It also has a chrome base, much too posh for a J Type?
However I have fitted it in place of the more modern one I had installed. It just fits in the door cover panel recess. I had to make a wooden backing plate as the switch mechanism and connections stick out some 15 mm below the base plate.
Here is the result.
I also have a larger base plate for what could be the correct light if someone has a plastic cover?
See picture below.
This one has the small knob on the switch lever , as the official illustration, while the one fitted above is just plain. This base plate is the same design but there is only a one electrical connection and an earth.
The plastic cover needs to be approx. 6 inches long and 2.5 inches wide to fit this base.
