Welcome to the board!
It could possibly be the switch, however all the Mariahs are equipped with an "SOS" circuit on the lights. That is, if you turn the nav lights on, then switch to only the anchor light, or vice versa, the lights will enter into "SOS" mode, and flash with the morse code for SOS. Fancy in one way, annoying in another. Could you be seeing this and thinking it's a problem?
If this isn't the case, I'd try and clean the contacts on the switch if you can gain access to it. Moisture can get into strange places on boats, and reak havoc on things that aren't sealed up, like switch backs and other electrical contact points. Check the connections at both the navigation light on the bow, and the anchor light on the stern and see if they've been corroded too.
Next step is to grab the trusty electrical tester and see if you're getting a solid signal, and then we'll all try and help you get things figured out!
