Rear wiring on Massey Ferguson 135

I can see where one of the wires is for The rear tail lights(as it becomes live with the light switch on) and they used to be indicators that were attached to this livewire I believe.

Hi and thank you for your reply, that is exactly what it is like but as the ignition switch only starts the vehicle and you cannot turn it off except for a pull stop, it is continually live. This may be meant to be but it would be nice to know if there is an in-line fuse for it.

rear work light housing has a 3-way toggle switch. Center is off, one way is white work light, other side is a red bulb behind the work light that shines through the glass lens.
That 1 wire powers the 3-way switch,
it does not go through the ignition switch. There should be a glass fuse type holder under the dash.

Is there a fuse holder in front of your left knee? Mine is a 10A glass fuse.
The rear worklight has 2 parts, one is the white work light, behind that sealed beam bulb is a red 1156 (I think) bulb which is for on-road use.
There should be a 3-way switch on the work light housing to control white/off/red conditions. This is powered from the ignition switch on my 1972 Perkins gas engine 135.
