An insulated cover protects against shock from accidental contact with live electrical circuits. This flashlight is tested to 1,000 volts to meet ASTM F1505 and IEC 60900. It is encased in a bright-orange, two-layer cover; take this flashlight out of service when the yellow layer becomes exposed. Remove the cover to change the batteries.
