Type H vs. Type L

Type H is Israel's own standard, used almost nowhere else -- one of the most geographically limited plug types in the world. A 1989 round-pin revision replaced the original flat-pin design, and modern sockets accept both, plus the ungrounded Europlug.

Type L, Italy's standard, uses three round pins in a straight line rather than a triangle, in two incompatible sizes (10A and 16A). Chile and Uruguay use the same physical design, though no independently confirmed national standard document defines it in either country.
