3rd Brake light flashing problem

Check the earths on the back lights.
First check, put on the headlights, and get someone to put on the brakes, see if any lights go out, if they do, that's the one with the poor earth.

Thanks for all your replies so far

we know the history of the car, so nothing dodgy happened at any point!

Update to the problem - all three brake lights are now constantly on (when the headlights are on). There is only a tiny amount of flickering, but hardly any worth noticing.

I hope this makes identifying the fault easier?

Probably the brake light switch

Some cars, the 3rd brake light flashes when the ABS kicks in.....
Also possible if the car has an ABS fault and had it's ABS warning light removed to get it past the MOT or to sell it on.

Easily check, just slam on the anchors and see if the wheels lock up

Doesn't sound like your issue (hopefully) but its worth a mention.

Not on a 2002 Corsa!
