27 ABSTRACT OF THE DISCLOSURE Methods and apparatus for selectively controlling the energization of a plurality of lamps in an elevator system, utilizing a microcomputer based lamp controller, and for detecting failure of the lamps while utilizing a minimum number of communication lines. A first communica- tion line synchronizes signals which are placed on the remaining communication lines. Signals indicating the need for lamp energization are detected by the lamp controller. When such signals are recognized by the lamp controller, the lamp controller prepares and places signals on a second communication line which requests lamp energization of the associated lamps, and it stores indications of the re- quests. Signals responsive to the detection of actual energization of a lamp are placed on a third communication line and directed to the lamp controller. The lamp con- troller logically relates signals detected on the third communication line with the stored indications of lamp energization requests to determine or test system integri- ty, and to detect lamp burn-out.
