Top up your brake fluid and check for any leaks around the clutch slave cylinder! If the slave is leaking you will notice some fluid underneath the battery tray on top of the gearbox.
A known problem!!!
the slave cylinder is really easy to check. its like a mine coke can, but the end of it is ridged rubber. Grab it and squeeze it, and if fluid pishes out, get a new one.
As above, the light flicking on and off like that usually indicates low brake fluid level.
