Intended Use

Fitment Notice
The standard C-Light is manually activated and does not turn on automatically when immersed in water. Customers requiring automatic water activation should select the ACR C-Light H2O model. Confirm the applicable approval and carriage requirements for the vessel, activity and operating jurisdiction.
When This Light Needs Replacement
Replace the light if the housing, lens, switch, seals or mounting points become cracked or damaged, or if corrosion is present inside the battery compartment. Replace the batteries whenever light output weakens, after extended storage or when the unit fails its pre-departure function test.
Installation and Use Notes
Install two fresh AA batteries according to the polarity markings inside the housing. Test the light before each outing and attach it securely where it remains visible and accessible while the life jacket is being worn. Rinse with fresh water after marine use, dry thoroughly and remove the batteries before long-term storage.
