If either one is bad, or if the connectors have separated, or if any of the wires coming out of the either switch are broken, the 4x4 indicator will not go on. Then, of course, the indicator itself uses a bulb which can burn out.

The pulse generator on the rear is used for the "hubs engaged" light, and I'm not entirely sure how that system works.

OK, good to know and thank you for the reply. Having said that, when we tested the transfer case we didn't notice a "Hubs Engaged" signal, either. For my education, I assume the hubs lock in either hi or lo gear?
