Just as SOLAS/MED lifejacket lights need high quality standards, leisure lights also need some form of legislation to cover their design and manufacture.Some years ago EN 394 covered this function for life jacket lights used for leisure and Health and Safety at Work applications. However, this document was made obsolete at the formation of a new series of standards – ISO 12402-1 to 10. ISO 12402-Part 8 specifically covers the requirements for all attachments to all of these lifejackets and floatation devices i.e. inflators, whistles and hoods etc. However, the section in Part 8 dealing with ‘Position Indicating Lights’ has remained blank.
