Buying Guide

Certification and compliance

Look for USCG-approved or certified marine distress lights when required by local regulations to ensure recognized visibility and legal compliance

Waterproofing and durability

Choose devices with high ingress protection (such as IP67) and rugged construction so they keep functioning after exposure to spray, rain, or brief immersion

Battery life and replaceability

Prioritize lights with long run times and easily replaceable or rechargeable power sources to ensure reliable operation during extended incidents

Signal intensity and visibility

Check peak candela or strobe intensity and flashing modes — brighter, high-intensity strobes improve detection range for nighttime rescue

Mounting and portability

Consider whether the unit includes mounting options, hand-held use, or a flag/attachment for making a visible daytime/board signal while remaining compact for storage
