This Pop-up bicolour navigation light has a mirror polished stainless steel AISI 316 case with a Technopolymer body. The LED nav light is suitable for vessels up to 20 metres in length using either 12 volt or 24 volt electrical systems. To use the pop-up navigation light simply rotate the central stainless steel plate to raise the light to its "in-use" position. This foldable navigation light utilises LED technology to produce two 112.5° arcs of bright LED light, which is more energy efficient and has a longer life than standard bulbs.
