High level brake light not working.

[belfastmark]

Hi.
Just noticed today that my high level brake light isn't working.
Going to get the wiring checked tomorrow though I was thinking
that it may not be wiring if the other two brake lights are fine ?
Are there any other possibilities I should consider ?
It will be getting looked at tomorrow so I would appreciate prompt
feedback on this one folks.
Thanks.
Marko.

brake pedal switch perhaps?

Cheers Herby.
Will keep that in mind. Heading to the autospark shortly.
Will update later.

Update on this post.
It turned out to be a wire which had died.
Got the initial problem, the brake light fixed but in the process
damaged the rear jet feed join. Got that sorted with a piece of
oxygen tubing and now she is good to go.
Next is nearside front hub/bearing then coolant temp sender then
petrol tank level indicator thing and possible offside front calliper then
panel filter finished off with an oil and filter change !!
Must go out the back to the money tree.
