Solution: Replace battery (Ensure battery is inserted according to the manufacturer’s specifications). B: The threads, PCB board contact or other contacts are dirty. Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.The HM23 is a multi-purpose AA battery powered headlamp that can shine a maximum 240 lumens a distance of 174 feet.
