Mace Night Defender features an LED light for enhanced visibility and accurate discharge during nighttime activities. This product uses a thick gel stream that adheres to your intended target. The OC pepper gel causes respiratory distress, coughing, impaired vision and an intense burning sensation on skin. The UV dye leaves a long-lasting residue to support identification. This product contains 20 bursts with a range of 18 feet. It is recommended that you replace or refill the formula after each use. A flip-top safety cap prevents accidental discharge.
