<VV> LED vs regular bulbs

[Smitty]

While pulling my dashboard on my 66 Monza I replaced the bulbs with LED 
bulbs.? That was ok for dash lights and turn signals, but for the GEN and 
FAN bulbs, they didn't work. The I discovered that the hot wire to those two 
bulb sockets was on the side and the ground was at the tip on the bottom 
(reverse).? An LED bulb won't work with reverse wires, a regular bulb will.? 
Am I correct?

Smitty Says;  the answer is in the name, LED.  Light Emitting Diode.  Diodes 
only pass current in one direction.
