612 Front Turn Signal replacement

Yesterday I was driving and turned my turn signal on to change lanes and a Light out warning came on the dash saying my front left turn signal was out and that I needed to see the dealer. When I got home I parked the car and turned the left signal on and it seemed to be working fine but the Light out remains on. Is there more than one bulb involved? Has anyone replaced one? How complicated is it? Many thx.

 

An update...yesterday I spoke with JR, my Service Advisor at Ferrari Palm Beach. He said that this bulb out warning light sometimes occurs when the computer senses too much resistance from the light bulb even though it is still working. Replacing the bulb should fix it. How much resistance can a 15 year old bulb have left? Answer: Enough to turn a bulb out warning light on...or perhaps it is just telling me its on its way out!! Nice feature!!
