ACR Firefly® PRO WATERBUG SOLAS

The ACR Firefly® PRO WATERBUG SOLAS is a SOLAS-approved marine strobe light engineered for water activation, automatically illuminating the moment the unit becomes submerged. Designed by ACR Electronics—a leader in marine safety and rescue equipment—this strobe delivers the high-visibility signaling capability that separates effective distress communication from unreliable alternatives when conditions are critical.

The PRO WATERBUG features four distinct activation modes: automatic water-activation mode (arms the strobe upon submersion), ultra-bright strobe, SOS strobe pattern, and steady-on mode for continuous visual signaling. This multi-mode design means you can toggle between automatic operation for hands-free deployment or manual control to preserve battery life and coordinate signaling with rescue operations. The innovative wide light emission pattern maximizes visibility across the 360-degree horizon, reducing the risk that Search and Rescue crews miss your location due to narrow beam geometry. At just 0.4 lbs and compact dimensions, the Firefly PRO WATERBUG integrates seamlessly into life jackets, liferaft emergency kits, or grab-bag survival gear without adding weight or bulk.

This product is essential for offshore fishermen, cruising sailors, commercial marine operators, and anyone transiting open water where rapid detection by rescue assets can be the difference in survival outcomes. Weekend boaters pushing beyond visual range of shore, fishing crews working night shifts, and liveaboard sailors benefit from the confidence that automatic water activation eliminates the need to manually trigger the strobe during an emergency. The SOLAS certification ensures compliance with international maritime safety standards, making it the preferred choice for both pleasure and professional marine operations.

ACR's Firefly line is recognized in the marine industry for reliability in saltwater environments and proven visibility in low-light and fog conditions—performance attributes that translate directly into faster rescue response times and successful outcomes for mariners in distress.
