Should work fine.  I've done it.  You just won't get into the 4 amp range 
to kick it back to 1 amp.  In fact you won't even get 1.  It will just flow 
as much current as it can { (12-Vdrop)/16ohms}.  Even though it's a simple 
circuit, don't forget the big watt Zener diode.  I've lazily and stupidly 
left it out and let the magic smoke out.  As long as the magic smoke stays 
in, electronics work fine.  But as soon as you let it out, things just 
don't seem to work.  :-)
