I looked into this a few months ago as a result of a discussion regarding power
inverters provided with a cigar lighter plug.
Some cars *were* provided with a cigar lighter type socket with a 10 amp fuse
(but no cigar lighter).
The original cigar lighters were supplied with a 30 amp fuse and cabling.
These lighters would light up bright orange in about 5 seconds and remain so
for several seconds afterwards.
Later cars had the socket but no lighter. They were supplied with a 10 amp fuse
and cabling to suit. Putting a normal cigar lighter (from an older vehicle) in
them instantly blows the fuse.
Then the Japs (notably Honda and Nissan initially) started to fit cigar
lighters that would run on a 10 amp supply (and other manufacturers followed).
They take about 3 months to get hot enough to light a cigar and go cold in
about 1 mS (ok perhaps I exaggerate a touch)
That's what happened. Make your own decision on what is and what isn't a cigar
lighter socket :)
