I sure can't think of one, Red. In my meremberment a 48 (about 3/4 inch) would be the biggest, and you'd have to have a real steady hand to do it in one touch and light the whole end. Considering that a cigar/cigarette lighter is less used to day for it's original purpose, and more as an aux-power outlet, standardization has taken over, and none would be larger that another.
