Light
OK mine has only 1 off and off push switch and both bulbs go on and the wall switch master switch.
I guess you could change the wiring to both if you need to but usually we don't keep all 3 lights on at night because too much light and we use 1 or 2 of the light as needed with on e over the galley sink and other 2 over the saloon and 1 moe to side.
Like I said to us we don't need that much bright light at night.
I have been adding led lights that use 2 AA batteries in my rear berth and bathroom and vee berth and all over to cut back on battery using,my wife doesn't like the bright lights at night,Wall mart special led in a package of3 or 4 are the best that we have found,2 settings.
We only just added the battery led from wall mart and work good in the rear berth for night call to head.
