Product ID:Subject: Broken light
Content: Light not working: night dive. At the end of one 35 min dive, my light would not turn off. After getting out of the water, I unscrewed the cap a couple of turns to lessen spring tension until the light turned off. I didn't need it again so I set it aside. A week after the dive I decided to take a look at it, but the end cap wouldn't budge. I fought with it for 10 minutes and finally got it unscrewed only with the help of vice grips. The inside of the end cap had corroded shut. I tried to clean the corrosion, but could not get it all. I thought I could salvage the light and still use it during camping trips. Even with the corrosion nearly gone, the light doesn't work. I know it's not a contact, LED or battery issue because the light will occasionally turn on (blinking twice) then nothing more. I bought this May, a month before I needed it.
