I don't know if you have the same light as our MS.. if so the light is easy to open (if you know how) first time was a learning experience. slide the lense back and allow it to come down. the bulb is available at home stores. it is a landscape bulb.. there are three wattages available.. the 11 watt is plenty bright for the light.. I don't now if a higher wattage is safe or for sure if the 11w is safe. ours is the same as the one over the kitchen sink. I plan to buy the lowest wattage bulb available to put over the sink. It is too bright for my taste. Of coarse all the small rocker switches control 12v items and the large paddle switches control 110 volt.
good luck and happy camping
all the time
