I had a 1978 Ferrari 308GTS that came with a trouble light in a black vinyl pouch. There was a special plug under the dash, and the electrical plug was this odd type that BMW also used on their motorcycles. The cord wasn't more than 6 ft long, so not much use. Never understood why Ferrari wouldn't use a normal 12vt cigarette lighter plug. The actual cigaratte lighter on a 308 was fixed, in the center console and you pushed it in to activate, and there was a hole in the center that would glow and get hot, and you stuck your cigarette in there to light it. It would shutoff automatically after several seconds.
A couple years later, I traded up to an 1987 Ferrari 328GTS and sure enough, same trouble light, but now with a traditional cigarette lighter plug. The console had a normal cigarette lighter like any other car. Push it in, it popped up and you removed it to light your cigarette.
Here is the odd BMW plug. I think it was for electric vests when riding.
