I have a Mitsubishi Strada 2014 four door pickup. Somewhere there is an intermittent short between the right taillight filament and the right brake light filament. Both reside in the same bulb and normally everything works.
However there are times when the taillight is on and depressing the brake pedal causes the taillight to fail while and the brake light does not light either.
I have removed the light assembly, inspected the bulb and the wires as they attach to the assembly and see nothing wrong. Last night is was not working. This morning after inspecting the bulb and seeing two good filaments, I reassembled and see no problems…
But this is not the first time it has happened. A friend had told me I had a light out last year and I disregarded it as all was working when I checked the lights out then.
Where can I look? How do I diagnose this?
