Have fun and impress your friends! With a red LED to port, green to starboard and an all-round white up top, this smart baseball cap illuminates in a similar way to the navigation lights of a yacht.
It won't comply with the International Regulations for the Preventions of Collision at Sea, but just might come in handy when you're in the dinghy rowing back from the pub. It will probably also cause some amusement at the yacht club!
