The invention relates to a navigation light with high safety and reliability for marine navigation. The navigation light with high safety and reliability for marine navigation comprises a floating plate, a mounting seat, a navigation light, a protection mechanism and a plurality of insect expelling mechanisms, wherein the protection mechanism comprises a protection plate, a buffer assembly and a plurality of connecting assemblies; the connecting assemblies comprise a connecting rod, a moving plate, a hinged rod and two first springs; and the insect expelling mechanisms comprise a connecting box, a piston, a support, a connecting rod, a nozzle, a fixed rod, an air inlet pipe and an air outlet pipe. According to the navigation light with high safety and reliability for marine navigation, theimpact of sea waves is reduced through the protection mechanism, the side overturning of the navigation light caused by too large sea waves is avoided, the safety of the navigation light is improved,the insect expelling function is realized through the insect expelling mechanism, and mosquitoes are prevented from adhering to the navigation light to influence the navigation effect when illumination is carried out.
