Ok got a yak week ago.. went to turn the lights on other day and only the red from nav light would come on.. .I check the wires and everything is tight.. If you press on the green nav light it will come on but then go off when you stop pressing any ideas?

bad connection for sure, wire might be broken inside the light where the wire enters the light on the inside, or a bad filament in the bulb wher you move it alittle it makes a connection and let it go conections lost, either way if pushing on the light itself makes it work its the light for sure weitehr it be worn out wire or bad bulb. wires can get old and break inside the jacket around them and cause problems seen it a million times, just thats my 2 cents from a union trained electrician :p

loose wire or connection. if its an led, there is no filament. chances you will need to take it apart and resoder the bad connection. gl
