Does anyone know the bulb sizes for the mast deck and running lights for a 2003 SO43? It would be nice to have them when I climb the mast.

Found a OM here at Jeanneau USA, that goes to the france site. But it is all in francais, I got a D in HS in francais. Needless to say, I can not read it. Nor did I see what appears to be the lightbulbs you are looking for.

You might try asking at jeanneau owners network - Home if you have not done so, or know about that site.

Good luck
