Q: The Compact Personal LED Light does not switch on after it has been used for a while.

A: There are several possible reasons that a Compact Personal LED Light will not switch on after it has been on for a while. Please go through the following checklist carefully: Are the batteries depleted? Even if the light has not been used, the batteries may be depleted over time. It is also possible that the switch was turned on accidentally when the light was stored away. Obatin a fresh set of batteries and replace with the ones in the light. If the batteries are fresh, check to see if the batteries are working properly. The tail-cap may have loosen up over time. Screw the tail-cap all the way into the body until it stops since the metal plate inside the tail-cap must be able to conduct with the body in order for the light to switch on. Inspect the inside of the tail-cap to ensure no foreign particle is physically blocking the conduction. Have you changed the batteries recently? If so, check the battery orientation. When inserting the batteries, be sure the positive (+) terminal is inserted into the light first. This is different than our Handheld Lights. Since LED has polarity setting, the light will not function if the batteries are inserted in the wrong direction. If you are still experiencing difficulties, please contact our customer service department.
