Abstract
The motor vehicle lights LED failure detector has a comparator block and an output characterisation block, with or without a protection block. The comparator block detects voltage drop in the lights electronic circuit, through reference to the characterisation block. EMBODIMENT - The comparator block has a diode, a Zener diode, and resistors.
