    Gents, '99 355 right side turn signals (front, rear and dash) are flashing double time. All other lights function properly. Hazard - including right side - flashes normal tempo. Before I venture into the 'hit and miss' abyss, can anyone steer me in the right direction? Thanks.

    This is often caused by a high resistance in one of the connections at the lights, most likely at the bulb itself. Try your tail lights first. Remove the bulb, clean the contacts on it and the socket (suggest you use one of the electronic liquid conditioners to enhance the contact and help prevent future corrosion). Might as well clean the connector to the tail light assembly while you're in there. I'd be willing to bet this will fix it.

    Or a bulb is burnt out.

    During the winter/colder season my 97 will flash very fast on the right turn signal.

    Once spring rolls around it flashes at normal speed.

    Italians + Electronics = fail.

    A quick google search brings up an almost identical fault on a UK F355 car on another, UK based Ferrari specialist website that has the Italian for "racing stable" in it's name - Only on the left hand side of the car: Fast flashing when the left side indicators are operated, as though a bulb has blown, but with no blown bulbs at all. Hazard warning lights flash at normal speed.

    The suspicion was that it was a poor/faulty earth on the left hand bulb assembly.

    To test it, they got a length of suitable wire and placed one end against a good earthing point on the car and then touched it to the earth side of the bulb assembly whilst the indicator was running.

    Straight away the lights went back to their normal speed, so the owner fitted a permanent additional earth to the bulb assembly and it cured the fault.

    It's worth trying, if only to rule out an earthing fault.
