Hi after success with the cv joint , moving onto other niggly bits , the left brake light has been inconsistently working then not , so used to give it a tap and woukd work now it’s just not working , bulb checked and replaced , took light off for a visual wire check no obvious issue found anyone have any experience in this issue ? Cheers
There are two filaments in the bulb, brake light one might be bust.
Get a test light to make sure you have power with the pedal depressed.
Some bulb holders have their own earth, check if yours is one and if it works ....
I was sort of thinking that if the actual light works then the earth is OK, he could check that also.

It's possible the fuse for that circuit needs replacing now after shorting out a few times.
Each side is independently fused
Each side is independently fused
Would the fuse blown still allow the light to work and just prevent the brake filament working ?

Yes each circuit is fused independently and also each side

It's a fuse for each brake side etc, fuse for each head light dip and main ..
If they are ok then probably a broken wire

A twin filament bulb can blow just one of its filaments ...
Yea I checked and put new one in just incase
Make sure that the bulb holders aren't 'worn' and holding the bulb off of the connectors, so it only contacts now and again ...

Check the contacts in the bulb holder for corrosion. I had an audi that was murder for it, had to clean the contacts up regularly
Did they fill with water like ours ?

Not quite that bad mate, the foam/rubber seal was never quite right on the one unit and it just got condensation build up
Ours had a manufacturing flaw that allowed water to by-pass the gasket/seal and into the holder ... drove us mad till we worked out what the problem was ...
