Left side brake light (solved)

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

If you have power to the bulb holder and a new working bulb then maybe you could tweak the connections in the bulb holder a little to get a good firm connection to the bulb.
Bear in mind it's just general advice as I don't know what your bulb holder looks like.

Well yea the bulb is working and on with the lights , just no brake light bit works when peddle pushed I tried wiggling wires to no avail

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

Would the fuse blown still allow the light to work and just prevent the brake filament working ?

If it is independently fused then yes.

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

The bulb works with the light on just the second filament don’t light up when pedal pressed , couldn’t see and dodgy wires either il have another look tommorow

A twin filament bulb can blow just one of its filaments ...

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

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 ...
