The usability of marine lantern has been improved significantly by using the LED bulb and applying IT technology, However it is hard to fix immediately when the failure occurs, and there would be some additional costs in maintenance. Therefore, alternatives for those problems are required. In this regard, in this paper, we proposed the integrated duel-function LED marine lantern that has main and auxiliary light source at the same time so that it can operate auxiliary light source when the main light source has breakdowns or malfunctions.
