Brake light?

[A31.8T]

Hi there guys, was just driving and a warning light appeared on the dash. Circular with an X marked in the centre. I'm assuming it's brake related because it came on whilst braking. Switched off engine and fired it back up again, no problems till I hit the brakes. Any ideas? Brake pads? Disc?

Think it's a brake bulb gone. Check out the thread called "weekend drive comes to a stop", where I pinched the following picture from:
