An awesome strobe from Pelican. This strobe is small, bright and will attach to just about anything. Perfect whether you are a boater or just need a strobe so people don't hit you with their cars. Super bright LED beam with red lens can be seen from over half a mile away. Submersible to 500 feet make this strobe perfect for boaters and divers. Two coin cell batteries will power this light for up to 130 hours (included).
