Thanks guys
Here is a break down of how they stand at the moment.
When the headlights are off and the brakes are applied I have,
Inners rings bright, Outer rings bright, Outer centres bright and high level brake light.
When the headlights/sidelights are on I have,
Inner rings on, Outer rings on, Outer centres off.
And when the head/sidelights are on and I apply the brakes I have,
Inner rings bright, Outer rings bright, Outer centres bright and high level brake light.
I still have the single reverse and fog as normal and twin indicators as normal too. I could of gone for twin reverse and used the inner rings as fogs too but to be honest I could'nt be arsed!! As it involved more wiring and a fair bit of coding and to be honest for the amount of time the fog light gets used it wasnt worth it, but I might have a play when the weather warms up a bit!!
