Abstract:

The present invention relates to a system and method for estimating the remaining life of a light bulb. The system broadly comprises a device for determining a physical condition of the light bulb while the light bulb is in a non-operating mode, a comparison device for comparing the determined physical condition of the light bulb to a reference physical condition for a light bulb of the same type near an end of its life, and a device for displaying an indication of a life expectancy for the light bulb. The system may be integrated into a vehicle or may be portable.
