Sometimes the plastic where the bulb mounts gets too hot and melts and distorts where the bulb holder mounts to the plastic housing. Take a multimeter and see if there is power to the connection. Another way to check is to disconnect the plastic housing from the car and leave the wires connected and wiggle the bulb holder and see if you can get the bulb to illuminate.

The bulb failure relay compares the current draw between one side of the car vs the draw on the other side of the car. If it sees a mismatch in amperage it illuminates the warning light. So when you power BOTH tail lights off of the same side you are exaggerating that mismatch and the warning light illuminates.

Sometimes that sensor is so sensitive that you have to make sure you have not only the same wattage bulbs on both side, but the same BRAND of bulbs.
