It is possible somebody took the bulb out because they couldn't resolve a fault on the ABS. Would suggest check bulb is in place or at least not blown. If new bulb comes on and stays on get a blink code out of the ABS ECU and go from there, probably an iffy wheel sensor giving an air gap fault but you won't know until you investigate it more thoroughly. It is worth going through the pain barrier on this one, after all your life or somebody elses may depend on your brakes - think about it!
Hi rite had the dash pod off to get to the light it had a bulb swaped it over with a known working bulb and still no light what would be the next most likley cause is there a fuse (checked the main fuse box only fuse missing is for the head light washers???? ) or relay hiding sumwhere???? 
thanks
thanks

I will assume you have ABS fitted.
Trace the ABS loom, check all the relays are present and correct and are working. Check all the ABS fuses are present and correct. I can't remember on a Disco where the respective bits are, on a RRC it's all under the passenger seat but I think the Disco has some of it? tucked up near the glove box.
If you're not sure if you have ABS then look underthe bonnet and trace the brake pipes in the engine bay from the master cylinder (left hand side), somewhere on the right hand side (when facing the vehicle) you should find the ABS valve block - you can't miss it.

I have a '94 and a '96 and neither have ABS fitted. I think Classic kev has given you some good advice.
:doh: Er what a complete t****er ive worked around cars long enough shoulda been the first thing i checked !!!! prob fixed!! lack of an abs pump gave it away!!! durrrr yepp what a muppet:doh: anway do have a real prob n/s/r light i have the 4 lights 2 top 2 bumper when you put youre foot on the brake the n/s top light goes out!!! took it all apart thinkin it was the earth at fault but when you have no earth the top side light still lights up and both the tail and brake light are live!!!!
