Blade fuse boxe featuring LED warning lights which illuminate clearly indicating blown fuses. The fuses are housed in a clear cover making the warning lights clearly visible.
Please Note: 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).
