Lifejacket lights may show a steady light or a flashing light. It must be white, as far as is practicable be visible all round and have a duration of at least eight hours.

The battery may be water activated——where the water either forms the electrolyte or completes an electrical circuit, or it may be a lithium battery or normal dry cell. Activation of the light may be by manual operation or automatically on immersion. Flashing lights must be provided with a manual switch.

But now the lithium battery is have to use for marine,cause dry cell is not stable.

Now I will introduce our lights YYYD for you.

Overall Performance & Requirement

     YYYD type lifejacket light touch water from light turn-off, flash mode.

     The light will be operational throughout the air temperature range -1℃to+30℃, and its luminous intensity will not be affected due to the changing of temperature and power source, and its normal working duration shall be more than 10 hours.

Installation instructions

  1. YYYD type life jacket installations will light fixed clip into fixed with life jacket, with cords of attachment prison, can be fixed lamp life jacket.

  2. YYYD type lifejacket lights use method: When the lifejacket light touch water, lifejacket lights automatically emit white light signal. Off switch: hand presses the OFF key, lifejacket light is in the closed position ( position OFF ).    

  3. Test methods: The jacket lamp touch water exposed to water lifejacket light emits white light signal. Battery capacity indicator light: means the battery capacity adequate (to ensure that the working time is greater than 8 h );Indicator light does not shine : the shortage of battery capacity ( cannot guarantee the work of 8h).
