Vehicle high intensity discharge lamps are available with three wire ballasts which emit a signal indicating proximate shutdown of the ballast and thus failure of the bulb energized by the ballast. The signal provides indication to a vehicle electrical controller which can be relayed to a remote facility which schedules replacement of the bulb.
