Intended Use
Designed as a personal distress and emergency visibility light for attachment to life jackets, survival gear and outdoor equipment. It is suitable for recreational and commercial marine use where a manually activated approved strobe light is required or recommended.
Fitment Notice
The standard C-Strobe is manually activated and does not switch on automatically when immersed in water. Customers requiring automatic water activation should select the ACR C-Strobe H2O model instead. Confirm the applicable carriage and approval requirements for the vessel, activity and operating jurisdiction.
When This Light Needs Replacement
Replace the light if the housing, lens, switch, seal or attachment points become cracked or damaged, or if corrosion is found inside the battery compartment. Batteries should be replaced when depleted, after prolonged storage or whenever the light fails its pre-departure function test.
Installation and Use Notes
Install two fresh AA batteries using the polarity markings inside the housing. Test the light before each outing and attach it securely to the life jacket or survival equipment where it remains visible and accessible. Rinse with fresh water after marine use, dry thoroughly and remove the batteries before extended storage.

Parts Desk Insight
A distress light stored loose in a locker may be difficult to reach during an emergency. Attach it directly to the life jacket and test it whenever the batteries or safety gear are inspected.
