ACR Firefly PRO Waterbug™ Solas Water Activated Rescue Strobe Light


Using wide light emission LEDs, new Firefly PRO strobes cut through foul conditions with a super-bright flash visible for over three miles.

With three activation functions, select between the ultra-bright strobe light or the SOS strobe to visually alert Search and Rescue of your location, and toggle to the Steady-On feature for close-up recovery operations. The cool white color of the LED strobe has no yellow tint, allowing the light to be seen at greater distances.  With the latest microprocessor and energy efficient electronics, the Firefly PRO operates continuously for over 56 hours—48 hours longer than SOLAS/USCG regulations.
