Hello Slevin
Is this a genuine spoiler with built in LED brake light?
It's a while since I fitted one but from what I can remember, you swap the wiring from the high level light behind the glass to the one in the spoiler?
The high level brake light is powered separately from the other brake lights by it's own solid state relay and as far as I know being LED it doesn't have a sensor for bulb failure like the other brake lights.
Does the warning come on all the time or just when you brake?
