Thanks for the input guys. After searching the archives and reading the bulb/no bulb controversy I found my setup to be a fibre optic as described by golden rule. The tipoff seems to be that the panel switches for sliding roof, antenna, etc did not have lights as well. All fibre optic and light supplied by the octopus light fixture behind the a/c. There is a daisy chain of lights that feed the ac panel. Four of the bulbs feed the ac and the middle bulb in the daisy chain fits in the octopus fixture behind the ac. Thanks again
