GQ Brake Lights

[Corsta0211]

Hey Everyone. I bought a new brake light assembly for the GQ in January and it has worked fine, however recently whenever I have the headlights on, the left rear brake light stays on. When I tap the brakes, the left brake light does nothing, it just stays lit. When the lights aren't on, both brake lights are fine. Obviously this needs to be fixed, I don't need attention from the cops. Help will be appreciated. It's a 1989 TD42. Thanks, Corey.

Is the light a combined park/brake globe. Then check earth for left light. Park light is earthing through brake light.

Hey Mate. You wouldn't happen to know where the earth ends up would you? It's a combined globe, yes.

Check the bulb itself for corrosion .

Thanks mate, there's none it's a brand new assembly and bulbs.

is the globe in the right way ? eg i've seen the wires backward so you get brake all the time with parkers. cheap Chinese stuff

You may be onto something because it's a new assembly the fault should be in the assembly.

Thanks for that, I'll check that tomorrow when I have some light. Would that be the plug?

could be wired wrong it could be just a backwards globe. if its wireing you can pop out the connecting bit with a pick or pointy object and swap for the correct one. test light is your friend

Most likely it's the globe. GQ brake light globe is a dual filament one. One for parking & one for brakes.
When a one end of a filament ends up fusing with the other due to a factory fault of the globe, above bizarre behaviour can be the result.

Swap the globe and I would say that will fix the problem.

One thing you can do to confirm or rule out it's the globe is to swap the brake light globes from the faulty side to the other side and see if the problem moves to the other side. If it does, then it's definitely the globe.
