    Bulb check system is causing it... there is no fix at present IIRC, are they all LED's or just the brake lights?

    I think the Vectra C is using PWM to control the intensity of the lights since its using 21w bulbs on low power when driving and full power when braking, and I think the direct cause is too low switching frequency on the PWM in the car for LED's - LED's are way quicker to turn light on and off compared to an ordinary bulb.
    The flickering when driving should be fixed by an capacitor-circuit connected to the bulb, but I have not the knowledge to supply any info here. The flickering after the engine is stopped is probably as many says, the CANbus.
    But it amazes me that no one or no bulb-companies has figured a way to get around this problem, I have trouble to believe that Opel is the only make with this technology.
    Does it work on the Insignia?

    Do you get rid of both the flickering and the warning on the bulb check system with resistors?
