According to at least one source (http://www.powerstream.com/Wire_Size.htm),
14AWG is good for 32 amps. Somewhere on
the lights or their packaging there should be a rating for their current
draw--if it's in watts, divide by 12 to get the
current--e.g. if one light is rated at 100W, the current draw would be a little
over 8A for one and 16A+ for two.
Voltage rating does matter, above the wire's rating the insulation may break
down (I suspect--but can't prove--that part
of the problems with Lucas electrics is below par insulation). Obviously, 150V
is plenty good for a 12V (actually
13-14V) system. If anything, landscaping wire might be more rugged than some
others. Make sure you wire so that
there's no chafing or rubbing of the wire, and a fuse or two would be a great
idea.
