If there is already a thread on this topic, please excuse me, but I/m not good at searching for old threads. The hazard warning switch on the center console of the 512TR can fail and the hazard lights will stay on all the time. When the spring loaded button is in flush the lights are off. When pushed in and released, it comes out a short distance, the built in indicator light comes on as do the four flashers. Push it in again and a built in catch holds it in the flush position and the lights go out. The failure occurs when the catch fails to hold the button in. When mine failed I held the button in by hand intermittently until reaching home. My temporary fix was to place a 1/4" steel ball on the button and hold it down with strong aluminum tape. This worked well. The switch part number is 61917100 and I've read it is the same for the 512TR, 328, and F40. Searching the Internet at various Ferrari parts sources indicated the switch was "unavailable". One site showed the list price to be $789.00. More searching of the Internet indicated the switch supply was nearly exhausted and as one owner termed it, "the price has gotten frightfully outrageous." Then I stumbled onto an Internet link that stated the switch for a 1971 BMW 2002 was identical except for the symbol on the button, The Ferrari symbol is a triangle and BMW has the word "Hazard" but the buttons easily unscrew and can be swapped. BMW part number is 61311356193 and a Google search will bring up lots of places to purchase if you don't have a BMW dealer nearby. Mine arrived in three days with shipping included for under $70. The factory embossed lettering on both switches was identical and box indicated manufacture was in Poland. It installed fairly easily and works perfectly. Another alternative is a repair of the old switch. Google in BMW61311356193SteveJenkins and open a link to "How to Fix a Broken Ferrari 328 Hazard Light Switch". At $70 for new, I opted for the new, but at $789 or "unavailable" I would have attempted the repair.
