Thanks,Frank,Yes it will be a new fitting just bought the set as you say the difficult bit will be hiding the cable runs,yes i have a spare switch on the dash i could connect to,also it could be easier to fit the stern light seperately so as to use less cable around the boat with a seperate switch.would not use the lights very often but it gives you an option if its getting dark and you over run on time.I will also need a searchlight type of lamp to see where i am going.
