No rear light

Is it just one side not working?

Yeah mate just passenger side brake works fine just no red when headlights are on

If you still have OE globes you'll find over the years the lead on the base of globe will wear away.
sometimes if you hit the lens it will come good, but a sign all globes may need changing if the same age.
Something a lot of ppl forget to do

All sorted the solder on the connection was preventing the power to flow through

I have a very similar problem to this, but my indicator and rear light isn't working. Brake light is fine. Where abouts did you find the solder connection? My globe holders look fairly well sealed up.. the wire disappears into the plastic and I can't see anything from there.

i had thne issue of none working taillights once and as i searched it was the wiring from under the seat to the lights
