Is this something that just happened recently or has it been this way since the boat was new? Or since you bought it?
If it's a recent condition, did anything else happen about the same time you started having this problem? Did you or anyone else work on the boat or the electrical system?
Lighting is about as simple as it gets as far as electrical circuits. Power comes from a source, through an overcurrent protection device, through a switch, through the lamp(s), and returns to the source. If the lights don't illuminate, the bulbs are burned out or there's an interruption in the circuit. You, or an electrician of your choosing, will have to examine the wiring and find and correct the problem. Having a volt meter and the knowledge of how to use it will simplify the process.
