Abstract: An adaptive method of detecting a lamp outage condition is implemented in a vehicle flasher system including a plurality of lamps. The method includes the steps of: a) initializing an adaptive flasher current variable when the vehicle flasher system is powered on; b) monitoring the vehicle flasher system to detect a driver flasher signal request; c) measuring current output from the plurality of lamps in the vehicle flasher system; d) determining whether the level of measured current is indicative of a lamp outage condition by comparing the measured current to the adaptive flasher current variable; e) setting the adaptive flasher current variable equal to the measured current if the measured current falls within a predetermined learning range, thereby compensating for resistance changes in the flasher system over time to allow lamp outage detection; and f) returning to step b).
