Check for power at the downstream side of the fuse block itself and if you have power there, then your only possibility is a broken wire that leads to the bow light.
...make sure where ever you are checking at is a good, clean connection.
I had what I thought was the same problem with my stern light (plug-in style). It turned out to be the male/female receptacles/contacts...not the wiring.
I cleaned them up...and ba-da-bing....lights!!!
Worth checking out.
