The switch on the Light Mine can stick when first being used, so I would first like to make sure that you have it completely pushed over to the “ON” side. Sometimes the switch needs to be pushed over hard, using the butt of your thumb. The switch can click once but needs to click over a little farther to stay on.

While it is possible to change the batteries in the Magnetic Light Mine, please be very careful. Replacing the batteries does run the possibility of damaging the whole unit. Although, if done with care, there should not be an issue. Pressing on the locking tabs with a flat-head screwdriver will open the body. Pressing too hard will snap/break the locking tab and/or tab receiver, this is the difficult part so be very careful. The batteries are LR44 alkaline. Silver oxide equivalents (SR44) can be used but do not mix alkaline batteries with silver oxide batteries. (Silver Oxide batteries will last longer but the initial brightness of the LED will be less) When removing the batteries, you will notice they are shrink-wrapped. Your replacement batteries will need to be isolated as well. Clear packaging or electrical tape works well, just leave the ends exposed for the electrical contacts.
