<VV> LED versus regular bulbs

[Richard]

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?
