This water activated marker light turns on when it comes in contact with the water and turns off when it is dried off. It can flash for up to 500 hours which far exceeds most marker lights on the market. 500 hours of bottom time is more than a lifetime of diving for most divers. This is a disposable marker light with non-replaceable batteries.
