Not so. The bean counters thought they would save a dime by omitting 2 bulbs from the inst' panel but didn't spend a single coin to omit a place in the inst' panel for them. Owners returned to complain. Service techs installed a lot of bulbs a no charge. The cost savings disappeared quick. The omit bulbs practice disappeared too. Anyway,,, A couple of warning lamps have their own ground source. Illumination and signal indicators ground at the inst' housing to dash. If illumination works signal indicators should also. Do you have a 69 Dart that didn't go back to the dealer for 2 more bulbs?
