You may encounter a few issues when using the dive lights. Try out some basic troubleshooting ways first. For something simple or common, you can fix it by yourself quickly.
*The dive light doesn’t turn on.
Check the batteries to see if they are fully charged, ensure the batteries are installed correctly and tail cap is completely screwed on to make full contact. Then, turn on the switch to try it again.
*The dive light flickers, or dims.
Check that the tail cap is completely screwed on to make full contact. Ensure the batteries and battery cradle are installed correctly, and make sure all contact surfaces in the torch are clean, especially the inside threads of the end cap.
*The dive light appears flooded.
If the light seems flooded with water, turn it off immediately. After returning to shore, unscrew the bezel and rinse the contents with fresh water. Allow all components to dry completely. Reassemble the light to see if it still works. If not, contact the manufacture to check more about returning and repairing.
*Switch seems stuck or broken.
A common problem is magnetic switches sticking. This may occur when diving in salt water, sometimes after a dive, salt may dry on the magnetic plates. Try to soak the light in hot water for 10- 15 minutes, then keep the light in hot water, depress or slide the switch on and off several times. Repeat it a few times. If this still doesn't work, you may remove or replace the switch according to the correct way.
*O-rings worn out
Keep o-rings clean and lubricated is the best way to avoid a flooded light. Clean and lubricate often. Replace o-ring when needed...
BTW, always recommend you to keep any proof of purchase from the manufacturers. With it, the warranty will go more smoothly.
