hello guys in a better mood for i have just discovered that led brake lights and cruise control do not mix in ef or a ba with the park lights on. In the ef the cruise will not engauge at all when park lights are on. In the Ba (xr6) the crusie will stay on when the lights are turned on but as soon as you disingauge the cruise then try to reset it the cruise will not come on. With the lights on already the cruise will not engauge at all. Tried and tested on an Ef falcon/fairmont and Ba Xr6. Why this is I do not know.
