My '65 Streamline has a dual 12V/110V lighting system. In most of the
fixtures, there are twin bulb holders, one DC and the other AC.
Recently, I replaced my existing light bulbs, both 12V and 110V with spiral
light bulbs. Already however, one of each type of bulb has died.
Are these spiral bulbs subject to failure due to trailer vibration maybe?
Anyone know?
