6 position LED warning Blade fuse
Input 100A max
Output 30A max per circuit
LED Illuminates upon failed fuse, giving a clear indication to which fuse has blown.
Please note that in order for the red LED to illuminate, a very small, current passes through the circuit so you may still register continuity across the fuse box terminals when a fuse is blown or no fuse is in place.
This limited current is completely safe but may cause connected LED lights to glow faintly (since they require such low current to operate).
