Regarding inspection and maintenance: Our company's products are thoroughly inspected before shipment to ensure there are no issues before they are released, and generally, there are no problems.However, during transportation, due to bumps, moisture, and other factors, some problems are inevitable.If the light source does not light up or only emits a dim light, please follow the following methods for repair: Before performing maintenance, please ensure that all the threads of the flashlight are tightly tightened and not loose. If some threads are not tightly tightened, it may also be the cause of the flashlight not lighting up or only lighting up dimly. 1. Check the battery: Make sure the battery has power and insert it into the flashlight in the correct direction. Do not use batteries of different brands, and do not mix old and new batteries. 2. Determine the fault: Unscrew the back part to expose the negative terminal of the battery, then use a metal piece such as a key or tweezers to connect the negative terminal of the battery to the exposed, unoxidized part of the flashlight body, and see if it lights up.If possible, it's a problem with the flashlight switch.Please follow step 3 for inspection. If it still doesn't light up, please check the solder joints between the circuit compartment and the circuit board for any open or loose welds. If there are any, please re-solder them to resolve the issue. 3. Check the tail cover switch: Unscrew the end of the flashlight, and you will see that there is a ring on the outer edge of the switch's copper cap Use scissors or a sturdy tweezer to insert into the two recessed points of the switch pressure ring and turn it clockwise. Check whether the switch pressure ring is loose and ensure that it is tightly pressed against the switch without any looseness. 4. Check for poor contact: When the flashlight does not light up or has poor contact, check whether the lamp head is loose, inspect the tail cap to ensure the switch is tightly screwed and well-connected, and ensure that the copper post of the tail cap is in good contact with the metal ring of the tail cap. 5. Other issues: If the above methods still cannot resolve the issue, please contact our customer service, and we will assist you in resolving the problem.
