Brake light adjustment

Hi All,

Just found out that my brake lights do work, but only when I push a long way down on the peddle.
I don't normally have cause to break that hard since I use engine breaking mostly.
Is there any way I can adjust the point at which the brake lights come on?
As a reminder, this is a late (1984) series 3.
I can't see any obvious switch protruding above the pedal and once again the Haynes manual is almost completely useless for this.

Thanks in advance.

is it on the servo

pdf Land Rover Manuals | Landroverweb.com
shows a switch above the pedal for non servo and a variant with the switch inside the engine compartment for the servo version.

Could be but I have no idea what I'm looking for :S
When I do find it I have no idea how to make it more sensitive, i.e. make the lights on on sooner/with less pedal travel.
As I mentioned before, the Haynes manual, which used to be good back in the days when I rebuilt mini's, is appallingly lacking in pictures and diagrams of some seemingly important things and has very little write up on them as well. This is one of them.

Thanks oxides, yet again fantastic assistance.
All fixed and sorted. It was indeed in the engine compartment. 1/8th turn and the brake lights work as expected
I've now book marked the PDFs you linked and will refer there in future rather than my crappy Haynes manual.

If it's anything like mine you need to check it once every couple of weeks...
