The External Light is a flashing LED Light, offering advances in reliability and performance. The LED ring comprises some 8 LED‘s mounted in a way to ensure a minimum light output of 4.3cd over 180 degrees. It is connected via a 65 cm lead to the internally mounted Interior Light and battery. This lead length can be varied subject to quantities required.- The external light is designed to produce a minimum of 4.3cd in all directions for 12 hours. The RL5 Internal Light and Battery (3.05.0402) also powers the external light, key part of increasing reliability and reducing costs. The two units are connected by a polarised sealed plug with a screwed locking ring, for ease of service and replacement. The performance of course meets IMO SOLAS standards, is fully MED/MER/USCG approved.
