What to know before buying

Listing details to confirm

The SOS mode is explicitly not Coast Guard certified as a safety device. The maker also describes a 3-to-4-foot unlit surface zone in one feature and a 3-to-5-foot zone elsewhere, while its stated light-field dimensions vary between sections. Treat those zone and coverage figures as unconfirmed rather than fixed performance specifications.

Aggregate ratings are favorable, but the sample is small and no written customer feedback is supplied. The ratings alone do not establish how well the light performs, how easy it is to deploy, or whether buyers found its eight modes useful. Those details matter for a 12V light whose positioning is part of the described setup.
