Everything electrical works perfectly except yesterday I noticed the main brake lights had stopped working, bulbs are fine, all connections I can check easily are good and the high level brake light works? I then realised the rear lights are also not working (same bulbs) as I said everything else is fine, all front lights, hazards all round, fog light and reverse lights.

Any ideas as I'm a bit stuck with this, no fault codes are stored just in case it's in any way relevant.

Thanks in advance for any help received.
