Narva 93642TP 12 Volt Model 36 LED Slimline Submersible Trailer Lamp Pack

12 VOLT MODEL 36 L.E.D SLIMLINE SUBMERSIBLE TRAILER LAMP PACK. The majority of L.E.D lamps are termed ‘sealed’ and would seem appropriate for applications such as boat trailers. Sealing the lamp however is not enough to ensure a lamp is submersible, as water can still enter the lamp via the connecting cables or via a pin hole in the sealing process as a result of ‘capillary action’.
