There are lights in these areas, depending which route the coach driver takes if you will see any.
If you are on the ferry crossing the river Shannon from Killimer to Tarbert you will see Tarbert lighthouse.
Here is a link to lighthouses on the west coast of Ireland where you will be.
www.unc.edu/~rowlett/lighthouse/irlw.htm We spent two weeks in Ireland last September. Did our own self drive tour. Managed to see over 70 of the Irish lights and climb 5 of them. Met some amazing people, lighthouse attendants and one Lighthouse Keeper (there are only two lighthouse keepers in Ireland, the rest are lighthouse attendants).
Hope the info helps, have fun.
