Look at the uper end of the brake pedal under the dash area
Check to see if Brake lamps work when brake pedal is pressed. If not gear shifter is locked for safety so replace fuse or repair brake lamp switch.
Probably cause by a worn out/defective brake light switch.
I am not sure on the later Discovery's but on my '95 Series 1, the culprit is the brake light switch. Easy to change - when it goes it does not allow the vehicle to move from park. Call any of the Rover parts catalogs and they can walk you through it.
Look under brake pedal arm for small plastic thing with a button. They can be adjusted (height) to control depression on said button when you push down on pedal. Press button manually & see if lights come on-if they do, adjust. if not replace. You can easily see how it is mounted & they basically plug into your elec.
its the brake switch censer under the brake peddle itself.
If I understand your post: The brake light is on constantly? If so, you may want to adjust or replace the brake light switch located at the top of the brake pedal.

You can try unscrewing the gear lever case putting some oil in there and try to losen it. Additionally: FIRST Check to assure that brake lamps are working when the pedal is pressed. If not, replace the brake lamp fuse or repair the problem with the brake lamp switch. For Safety the brake lamp switch is tied into a shift lock on most modern autos preventing the auto being placed into gear unless the brakes are applied.
brake light switch is mounted by the brake pedel remove lower panel above brake pedel and then you will see the switch should be able to turn the switch to replace
My 1995 Land Rover Discovery was stuck in "Park" because the brake light switch was faulty. Ordinarily, you must step on the brake to shift out of Park. If you depress the brake pedal and your tail-lights do not light up, it's likely because the switch is broken. The switch is located near the hinge of the brake pedal; underneath the steering column. Your local auto parts store should have a replacement; I bought two at $10 each... and keep the spare in the glove box in case this happens again.
