Designed to enhance visibility and safety during crew evacuation, the "70030" POSITION-INDICATING LIGHTS FOR LIFEBUOYS by Lalizas Hellas S.A. are essential for ensuring that lifebuoys can be easily located in the water. These lights are IMO-approved and certified according to SOLAS standards, with a model number of MEDB000052W, as verified by DNV. Additionally, survival equipment such as flares, water, and rations can expire. To maintain the reliability of these position-indicating lights, annual servicing at an approved service station is mandatory (SOLAS/MSC.1/Circ.1328). The HRU must be replaced according to the manufacturer's interval, typically every two years, while the entire lifebuoy system should be recertified or replaced every five years. The "70030" POSITION-INDICATING LIGHTS FOR LIFEBUOYS are designed with these stringent requirements in mind, ensuring they remain a trusted safety solution for maritime operations.

What our service work and the manufacturer documentation say about keeping this model running.
These lights are sealed units and are checked, not overhauled. SOLAS III/20 requires the monthly inspection: the light operated where its design allows a test without consuming the cell, the lamp and lens checked for clouding, the bracket and its lanyard checked for corrosion and for the lanyard having gone hard, and the expiry date on the body read. A self-igniting light has to work for at least two hours at the luminous intensity required by the LSA Code, which is why a cell past its date is treated as a failure even if the lamp still lights. Units mounted high or on an exposed bridge wing age faster through ultraviolet and salt than the date alone suggests, so the lens is worth a close look at each inspection. With a maximum stowage height of 80 m in this approval, check also that the unit is actually mounted at or below the height it is approved for - the figure limits where the light may be sited, and a light moved during refit to a higher deck quietly leaves its approval behind.
Where the design allows it, the battery pack is the only renewable part and is fitted by date, not by condition. On fully sealed units there is no spare at all - the complete light is replaced at expiry, and that is the item to carry. Besides the light itself, keep the mounting bracket and the lanyard: the bracket corrodes at its fastenings and the lanyard stiffens and chafes where it passes the rail. Order lights as a batch matched to the lifebuoy outfit so that the whole set does not fall due in separate months. One constraint belongs to this approval in particular: the unit is rated for stowage up to 80 m, so a replacement has to carry that same rating. A light of similar appearance approved for a lower stowage height is not a substitute at a high mounting position, and the difference is not visible on the shelf.
